Knop 14x6.6cm

Wasn't sure about the 6.6cm width at first, but that pronounced bulge fills you in a way that's hard to describe until you try it. The firm pressure is the real selling point here, holds steady instead of giving way. Genuinely exceeded what I expected.

That rounded head delivers exactly what the description promises—instant filling, and the 14cm length makes the deep pressure last through every movement. Firm enough to feel substantial, but the shape glides in smooth and stays put.
