History / About
Per Polyform, the A4 is named as a representation of a blank page for a fresh start. It is a 6061 aluminum body with a hollow Polyamide 66 nylon ring, and uses the new PF20.6 response pad, developed for a snappier bind than conventional 19mm pads. An extra pair of white silicone pads, a random sticker design and string are included, and a fatter string is recommended. YoYoExpert lists the release as April 2023. Yoyo Store Rewind (Japan) says Polyform was launched by Jeffrey of Luftverk and the A4 is its first release.
