About
The J1 is YoyoFormula’s entry-level responsive aluminum, machined from 6061 alloy with anodized finishes and unique laser-engraved rim patterns for each colorway. Five “elemental” colorways — Earth, Metal, Water, Fire, and Wood — each carry distinct engraving motifs. The slim responsive bearing can be swapped for a standard Size C for unresponsive play, making the J1 a two-stage learning yo-yo.
