Firefly Prince - Nút bịt hậu môn nhỏ màu xanh phát sáng trong bóng tối 10.9 cm

The glow effect is genuinely impressive—even a quick pass near a window leaves it bright enough to find in the dark. Silicone feels firm but gives just enough, and it works fine with water-based lube. Cute little thing that does its job.

Charged it under a lamp for a bit and the glow is seriously fun in the dark, plus the silicone feels firm but gives just enough. The 10.9 cm size is perfect for beginners like me, and being able to use any lube was a nice surprise.
