How BrainChainz Works
Note: BrainChain clips fit all cap brims. Clips are pushed onto brim. If clip is loose because clip opening is too large,press clip opening together a bit with your fingers till opening is smaller and then push onto brim. Care should be taken if brim is made out of leather or other soft materials to widen clip opening before pushing on brim as excessive force can ruin the materials.
BrainChain crowns fit almost all caps. Open the clasp on the crown and then pull open the crown from outside the hinges. Place crown over the cap pin and close it as the crown wedges go under the pin. After closed shut the clasp . Don't use excessive force to close the crown as it can damage the materials.
