Will the spacer ruin the ring itself?

No. The ring just sits in the spacer.

Can I buy only one size?

The answer is no but I wish they sold it by sizes because I need only the XS.

Knowing how many sizes are included, how many pairs of each size are sent, as other brands send duplicate or more of each size.? Thank you!

They were terrible...wouldn't fit.
