Abstract
A convex shell for use in a base plate of an ostomy appliance includes an annular ring with a through-going hole and a plurality of grooves extending transversely across the annular ring. The grooves alter the flexibility of the annular ring as a first portion of the annular ring is folded around a folding axis toward a second portion of the annular ring.
