摘要

Replaceable coat consists of a convex curved surface on which knobs and jewelry items can be attached. An appropriate material thickness helps in converting convex shaped upper surface (1) into concave surface by means of simple pressing by the finger whereby due to pressure applied, the inward edge element (2) gets bent into outward direction.
