so when i had my yoyo it had the o ring falling off over and over. my mthed does not damage the yoyo.
NEEDED SUPPLIES: YOYO WITH SPOT FOR RING,RUBER O-RING 1/16 is what i use,super glue,scissors and about 2 minutes of your life.

Step1. pick up the o ring and cut out about 3-6 mm depending on yoyo slot.

Step2. Use a small drop of glue to make a smaller o-ring put it on and test it.

Sometimes the ring maybe a little small looking but it will fit once stretched and completely dried.

Or fill o-ring groove with silicone.

And since we are buying o-rings anyway it would make more sense to either buy silicone or buy an o-ring that already fits. YoYoJams use #11 (3/4x9/16x3/32).

;D thx for feedback but where i live we dont have any good fiting o rings iliv in the midlle of umatilla

If there is an auto parts store there then you have all you need. Or a hardware store.
