小直腸拡張器セット（サイズ1〜4）

The medical-grade material gives just the right amount of firmness without feeling rigid, and having four sizes to progress through made the whole process much less intimidating. I appreciated that the smallest one let me start slow, and the set's case keeps everything tidy for storage.

The graduated sizes in this set made working through the progression feel manageable, and the medical-grade firmness gives just enough structure without being uncomfortable. I've used them with plenty of lube and the smooth surface makes cleanup a breeze.

Went through all four sizes over a couple of weeks, and the graduated set made the whole process feel way less intimidating than I expected. The firmness is perfect—solid enough to control but the smooth surface glides comfortably with lube.
