Zwarte obsidiaan - Yoni-ei - niet geboord

I was pleasantly surprised by how smooth the black obsidian feels against the skin, and the weight provides just the right amount of internal pressure for muscle awareness. The non-drilled design keeps the surface completely seamless, which makes cleaning and handling much simpler. A solid purchase

The non-drilled design was a big plus for me—no awkward cord to deal with during use. After a few weeks of consistent practice, I've definitely noticed stronger pelvic floor engagement and more intense sensations. It's a simple tool, but it delivers exactly what it promises.

I wasn’t sure what to expect, but the smooth, polished obsidian feels really nice against the skin and the non-drilled design makes it comfortable to hold. After a few uses I’ve noticed better muscle control, which has been a pleasant surprise. Definitely glad I gave this a try.
