Tantus Inner Band Trainer Onyx Silicone Trainer For Graduated Stretch

A Soft Silicone Trainer With A Gradually Widening Shape, Harness-Compatible Base & 22.9 cm Length

Want a fuller feel without jumping straight from comfortable to colossal? The Tantus Inner Band Trainer is shaped to gradually stretch and fill as it moves in, giving you more control over how far you want to progress.

Made from Tantus 100% Ultra-Premium Soft Silicone, this sleek trainer combines a smooth widening body, 5.1 cm diameter, broad 7.1 cm base, and harness compatibility.

Whether you enjoy larger toys already or want something that helps bridge the gap toward a fuller size, its simple shape and softer silicone make progression feel far less intimidating.

“Start smooth, build gradually, find the fullness that feels right.”

Tantus Inner Band Trainer Onyx Key Features:

✅ Graduated Stretching Shape: Designed to gradually widen and create a fuller sensation as more of the toy is inserted.

✅ 22.9 cm Length: Long overall design gives you room to explore the shape progressively rather than all at once.

✅ 5.1 cm Diameter: Fuller maximum size suits those wanting to explore a more substantial feel.

✅ 100% Ultra-Premium Silicone: Made from Tantus’ own premium silicone formula for softness, flexibility, and easy hygiene.

✅ Soft Flexible Feel: Softer silicone moves more naturally with the body than rigid materials.

✅ Harness Compatible: Broad base allows the Inner Band Trainer to be used with a compatible harness setup.

✅ Wide 7.1 cm Base: Generous base gives you easier handling and support during use.

✅ Hypoallergenic and Hygienic: Tantus lists the silicone as hypoallergenic and hygienic.

Product Details

The Tantus Inner Band Trainer Onyx is all about progression. Its sleek shape gradually fills out as it enters, letting you explore a larger sensation without the abrupt jump you get from toys with a pronounced head or sudden bulge.

That makes it a strong option if you already enjoy moderate sizing and want to work towards something fuller, or simply prefer a smooth gradual build instead of heavily textured stimulation.

The toy measures approximately 22.9 cm long with a 5.1 cm diameter, while the broad 7.1 cm base provides stability and makes it suitable for compatible harness setups.

Tantus’ 100% Ultra-Premium Soft Silicone gives the trainer some flex as you move and position it, keeping the focus on gradual fullness rather than rigid pressure.

Best For

Best for gradual stretching, fuller sensations, smooth silicone toys, progressing towards larger sizes, harness play, soft flexible materials, and anyone who prefers shape and fullness over ribs or heavy texture.

Not Ideal For

Not ideal if you want a small beginner toy, pronounced texture, vibration, or an extreme oversized design. Inner Band Trainer is made for a smooth, progressive build towards a fuller 5.1 cm diameter.
