Use a piece if duct tape and let it sit on the cap for a few minutes then pull. Or use a suction cup to pull it off.

Suction cup works a treat.

They do, sometimes they are harder to get off, that’s when duct tape comes in handy :). I have also heard the severe caps are harder than usual to take off. Correct me if I’m wrong ;).

I got them of but I had to destroy the caps.

I use a slightly larger suction cap. Takes up almost the entire surface of the side cap.

I thought it was Der-lin.

It’s delrin, although that’s actually a brand name. The generic name is polyoxymethylene.

At one point i saw you post this and I started spelling it that way until I looked at the yoyo.

Del-Rin.

I thought the generic name was Acetal…

I believe Acetal is another brand, but polyoxymethylene is the scientific name for the specific type of polymer (plastic).
