will the yyj silacon stickers fit on the dv888.

Why not use the ones that come with it?

Icthus speaks the truth.

But to answer your question, if you bought your Dv888 any time recently (2010), then yes they will fit.

My personal recommendation would be to get yourself an actual tube of silicone and learn how to silicone response your yoyos. That way you’ll be able to use silicone and know that it will fit in any response groove you want.
