These response pads are stickers. Simply remove the old pads, remove the backing of the new response pads to expose the adhesive, and place them in the yoyo.
White response pads come default in most yoyos, as they offer excellent play for an affordable cost and are the best all-around response pad.
Blue response pads have an overall grippier feeling than other response pads, maintaining that “new response pad” feeling for longer than other colored pads. Recommended for players who like tight binds over a long period of time.
Green response pads are the original thick pad designed by YoYoFactory for most of their responsive models.
