بيضة اليوني - حجر السج الأسود - مثقوبة

The drilled hole makes inserting and removing it feel secure, and the smooth obsidian surface is surprisingly comfortable. I’ve noticed a real difference in muscle awareness after just a couple of weeks of daily use.

The drilled hole makes it easy to attach a string for safe removal, which I really appreciate. The weight feels substantial, though I wish it came with a storage pouch to keep it clean between uses.

The drilled hole is definitely a plus, but I wasn't sure about the smoothness at first—it's actually more polished than I expected, which makes it comfortable to use. Took a couple tries to get the hang of it, but the muscle engagement feels noticeable.
