The stretch on this thing surprised me — it goes well past the 13 cm and still snaps back. Being able to squeeze and twist it however I want makes it way more adjustable than the rigid one I had before.

Wasn't sure about the TPE at first but it feels surprisingly soft and not sticky at all. The ripples inside are subtle rather than aggressive, which works well for a slower session, and the 13 cm length stretches way further than I expected when you squeeze it.

The stretch on this thing is no joke, you can squeeze and twist it however you want and it just springs back. At 13 cm it's roomy enough without feeling loose.
