The depth trainer (11 in)

Honestly i was worried it all wasnt going to fit at first and I'm pretty amateur when it comes to anal but with some lube, time, and analeze it all fit and was pretty comfortable! The texture was more enjoyable than I thought, but my only issue is that the soft silicone is a little difficult to use force on. For any other toy, like the sentinel, they're just fine with force and supporting themselves, but I guess because of the lack of support, the Vine depth trainer falls over and bends on itself (it isn't a huge issue it's still perfectly useable, just an aesthetic issue). Overall, it's fantastic and really recommended, even for beginners!

Great toy terrible shipping.

The toy's a 5/5 it's fantastic for depth training, not too stiff but not too floppy to where it's difficult to use. BUT it took over a month to arrive which was disappointing to say the least. Other high quality brands I've ordered arrived in a matter of days. This knocked a star off for me.

A quick heads-up, adventurer: every piece we craft is handmade with care and chaos, so it can take up to 14 days to forge your order.

Once your creation is ready to embark on its journey, we’ll send you a tracking scroll (email) so you can follow its every move. After that, it usually takes 2–3 working days to reach your doorstep — not counting the crafting time, naturally.
