Five points description
  • Built for gradual size expansion — Rex starts narrow at the tip and widens steadily to 2.4" diameter at the base. You control how far you go. Every session can be a different experience depending on your depth.
  • 8.9" insertable, 7.7" circumference at maximum — substantial scale across the full taper. The widest point delivers a genuinely full, all-around stretch for users ready for it.
  • Realistic skin texture from tip to base — raised veining, natural skin folds, and flesh-toned gradient coloring make Rex one of the most tactilely detailed tapered realistic dildos in this size range.
  • Dual-density construction that holds its shape — C2 outer layer gives with pressure; Shore A 25° inner core maintains structure throughout. At 2.51 lb, Rex has the weight and presence behind every stroke.
  • Full suction base, O-ring compatible — mounts to any flat surface for hands-free use. O-ring compatible (2.4" inner / 3.6" outer) for harness and partnered play.

What Makes Rex a Different Kind of Tapered Dildo

A tapered dildo gives you something fixed-diameter toys cannot: a choice within a single session. Rex widens from a slim tip to 2.4" diameter across 8.9" of insertable length — where you stop determines what you feel.

Gradual expansion, fully in your control

The taper is slow and committed, not steep or sudden. The skin folds and surface variation on the outer layer mean the widening registers tactilely as you go deeper — your body follows the taper rather than bracing against it.

Surface detail built to engage

Raised veins run longitudinally from glans to base, with natural skin fold variations across the shaft. The flesh-tone gradient — lighter at the tip, deeper toward the base — gives Rex the kind of visual and tactile authenticity that a tapered size expansion dildo at this scale should have.

Dual-density that holds through the full length

The C2 soft outer layer gives with pressure; the Shore A 25° inner core maintains structure. At 2.51 lb, the weight behind each stroke is constant regardless of which part of the taper you are using.

Who Will Love These Tapered Dildos

You want to explore size without committing to it

Rex lets you choose your girth by choosing your depth. Start at the tip, move deeper as you are ready, and find your threshold within a single session. Over time, that threshold tends to move.

You want a girthy tapered dildo with realistic detail

At 7.7" maximum circumference, Rex reaches XL range at full depth — but the taper means that girth is earned, not demanded. For users who want the sensation of significant size but need the progression to get there, this is the specific answer.

You want a flesh-toned tapered dildo with realistic detail

The gradient finish and detailed veining make Rex visually distinct from abstract tapered designs. For users who want a flesh toned tapered dildo that performs and looks the part, the combination here is deliberate.

How to Use Rex

Start at the tip, let the taper guide you

Apply water-based lube to the full shaft. Begin with short, shallow strokes in the narrower tip zone. Let your body set the pace for moving deeper — there is no requirement to reach full depth.

Use depth as your intensity dial

Find the point on the taper where the stretch is present but comfortable. Work at that depth before going further. Rex is designed to be used at whatever point works for you today.

Lube the full shaft, reapply often

At maximum girth, friction accumulates faster than with fixed-diameter toys. Apply along the entire 8.9" length before you begin. Reapply every few minutes as depth increases.

Mount it, adjust the angle first

Press the suction base onto a clean dry surface. In a riding position, body weight naturally controls how far down the huge tapered dildo you go — intuitive depth control without manual effort. Lock the angle before pressing to secure.

Rex does not ask you to commit to a size. It asks you to find yours.

FAQs

Is Rex suitable for beginners?

Rex's tip is approachable, but the maximum diameter of 2.4" at full depth places it in the Intermediate to Advanced range. If you are new to tapered dildos, Rex can work as a depth-limited experience — use it in the narrower tip zone only until you are ready to go further.

Can I use Rex with a harness?

Yes. The base is O-ring compatible — 2.4" inner diameter, 3.6" outer diameter — and fits most wide-format harness systems.

Frequently Asked Questions

What material is Rex made from?

Rex is made from Liquid Silicone Rubber (LSR), grade TBL-8870, a body-safe, non-porous, platinum-cured material tested to CP65, FDA 21 CFR 177.2600, EU REACH SVHC, EU RoHS, and covered by 13 SGS/TÜV SÜD reports.

Is Rex body-safe?

Rex is body-safe because its LSR exterior is non-porous, phthalate-free under CP65 and tested to FDA 21 CFR 177.2600; the LSR is platinum-cured and covered by 13 SGS/TÜV SÜD raw-material reports.

What are the Rex dimensions?

Rex measures 28.4 cm overall length, 22.6 cm insertable length, 19.5 cm mid-shaft girth, 6.1 cm shaft diameter; the full parameter table above lists weight, O-ring size and Shore hardness for accurate size matching.

How is Rex controlled?

Rex is a non-electric silicone dildo with no motor, battery or app control; it is used manually, which keeps the design simple, body-safe and easy to clean between sessions. Controls are positioned for simple one-hand operation during use.

Is Rex platinum-cured?

The LSR exterior of Rex is platinum-cured (addition-cure), not peroxide-cured, a cleaner process that produces a stable, low-odour, body-safe silicone; the platinum-curing process is supported by third-party process reports. This reduces residual by-products and supports a stable, skin-friendly surface.

What certifications cover Rex material?

Rex LSR material is covered by 12 SGS reports and one TÜV SÜD report, including CP65, FDA 21 CFR 177.2600, EU REACH SVHC and EU RoHS; the full raw-material ledger is at sustory.com/pages/compliance-certifications.

How should Rex be cleaned?

Rex should be washed with warm water and mild soap before and after use, rinsed thoroughly, dried with a lint-free cloth, and stored in a cool, dry place away from direct sunlight and other silicone toys.

Suction Base FAQ

How strong is the suction base?

This toy uses a suction base designed for clean, smooth, non-porous surfaces such as tile, glass or polished hardwood. Press the base down to push air out; the seal is designed to hold the toy in place for hands-free use. It is not a permanent mount and may release on textured, dusty, wet or curved surfaces.

Care & Maintenance

Rex is made from dual-density silicone — body-safe, non-porous, hypoallergenic, and free from phthalates or latex. The C2 soft outer layer and Shore A 25° inner core are molded as a single integrated unit.

Wash with warm water and mild soap after every use. Rinse thoroughly across the full veined surface — the raised texture detail holds moisture and should be cleaned carefully. Pat dry before storage.

Store separately from other toys in a cloth pouch or original packaging. Water-based lubricant only — silicone-based lubricants degrade the outer layer over time.

Excellent dual-density construction. It’s a little on the soft side, but the firmer core provides support, and the suction cup handles the weight really well. Love iit!!!

Terrific toy! The length and gradually tapered thickness are just right. It cleans easily with soap and water, and there’s no odd smell. It also seems to have some kind of internal rod.

Absolutely beautiful! This is the largest and most realistic piece in my collection so far. The coloring is stunning, and the silicone has just the right amount of softness. I’m not sure I can manage the size yet, but I’m determined to give it a try!

The curve is noticeable and aligns well for targeted stimulation, while the detailed texture enhances the experience without being overwhelming. Despite its weight, the large suction cup stays firmly attached to smooth surfaces and never came loose during use.

It's a bit heavy, but the suction cup still holds it up perfectly, and the silicone feels top-quality. Looking forward to trying it out. ??

This has been the most thrilling thick dildo I've tried in a while. The way the girth changes along the shaft creates an amazing sensation. It's realistic through and through, with a beautiful color and design, and the curve is fantastic. Everyone needs this in their collection.
