Infinity Weight - Kasm
Counterweights that look like mini versions of the Kasm! This version only weighs about 8.5g, which is specifically designed for return tops that are lighter than traditional 5A. (Regular Infinity Weights are about 10.5g).
Their constructions are identical to actual return tops — two halves screwed together by a nut and a bolt. The core can be substituted with a chain attachment part (included) so it becomes a keychain!
