Friction sticker coming off

I have a Duncan Raptor, and the silicone friction sticker isn’t sticking. It’s coming off and flopping around as the yoyo spins. Is there a special kind of glue I should use to put it back, or get new stickers? If I need to replace them, are they 12 or 13.7mm, I can’t tell.

You probably need new stickers. The Duncan Silicone Groove (SG) Stickers are the recommended replacement. Clean the surface before you put the new ones on.

Thanks cool. I’ve only played this for about 20 hours, I hope I don’t have to replace it that often.

You shouldn’t if u clean out the grooves before putting in new pads.
