gavian SG Increases ur grip strength. comes in a pair in a box. Going for $8! Still looks new. Used once or twice only.
xchangehub SG it's only worth if unless his handgrips are more than 40kg i bought from daiso $2 for 30kgs
gavian SG hmm there are no weights attached just a gadget for u to squeeze w ur hand. the gadget restrains ur hand when u squeeze it.
