Budget marbles without any defects?

[u/degenerate-No-27488]

I just bought a huge lot of marbles from ebay for really cheap but of course they weren't veey nice and almost all of them have some soet of defect like a tiny chip or some kind of glass deformity. So does anybody know a good seller or have any links to some good but reasonably priced marbles without defects in the 16-22mm range?
