I got a magic yoyo n9 a little while ago and took the z stacks off because they were being really noisy and I honestly didn’t have any use for them. So I put the parts in a little bag. Today, I decided to put the stacks back on so I got the back and discovered that I only have one o-ring. Not really sure what to do now. Does anyone have any tips or ideas to help me? Thanks

Buy a new o-ring in just like you would for hub stacks.

Will any o ring fit?

will the yyf o ring fit on my hubstack post?

Just compare the one you already have to other orings till you find a match

Go to lowes and either match yours, or get the smallest size and see if its the same.

Don’t buy them, you can get more for cheap and lowes.

ok thanks ill try it
