What can I use as PSG/ Astroid Weight rings?

Hello,
I was wondering if anyone had any experience with adding more weight to their adegle psg and/or astroid, what they used, where they got it, etc…
Thank you!

Well anything really it just needs not fit. Have you tried big o-rings, or mod glow sticks?

I’ll try the o-rings. Thanks for your help!

Where would you get o-rings?

You can get fat o-rings at the hardware store - plumbing section. They are usually in a box with a wide selection. Look for 3/16 in. thick rings. take the yoyo with and see what fits.
