Master Series PeepHole 透明中空肛塞 - 透明

The hollow design is really interesting—it lets you see through it while still feeling securely filled. The size is perfect for me as a beginner, not too intimidating at all. Super easy to clean too.

I was surprised by how comfortable the hollow design is—it stays in place without any discomfort. The clear material looks intriguing and makes the peephole feature even more interesting to explore.

The smooth surface makes insertion much easier than I expected for a first-time plug user. I really appreciate how the hollow design adds a totally different sensation during wear.
