As we release the previous 7S design by Eren years ago. Eztrik got good feedback form market & players. EZ short for ‘easy’, that’s why EZSPiN come to us again. We really want to make a modern design with the popular shape and good quality for world wide players. The original prototype was based the other 2 successful design, the V6-Petrichor & 8S-Vanquish. Front design update from Petrichor and distributing more weight to the outer ring, which make the yo-yo much more spinning time.Side shape you may find updating from Vanquish,which has a bigger width in the A-zone.
