Description

The Tantus Silk line is as simple as dildos get: a smooth, gently tapered shaft with no veins, ridges or curves, so it glides in easily. Tantus made it as a first dildo that doesn’t feel extreme. The Large is 1.5 inches wide and 7 inches long.

It works in a harness and for vulva or anal play, and Tantus says the Silks are safe to use as dilators. This is the onyx color, in 100% silicone that you can boil or put in the dishwasher.

TANTUS SILK QUESTIONS

How big is the Tantus Silk Large?

1.5 inches in diameter and 7 inches long. The Medium is 1.1 x 5.25 inches and the Small 0.8 x 4.25 inches.

Is it a good first dildo?

Tantus designed the Silk line as a first dildo: smooth, simple and unintimidating. The Large suits people who already know they want a fuller size; others may prefer the Medium.

Can it be used as a dilator?

Tantus says the Silks are safe to use as dilators. If you are using one for a medical reason, follow your clinician’s advice on size and routine.

Is it harness compatible?

Yes, and safe for vulva or anal play.

Which lube should I use?

Water-based. Silicone lube isn’t recommended with silicone toys.
