12 Pack Clear Castor Cups with Felt Pads - 44mm Heavy Duty Furniture Floor Protectors for Chairs, Tables & Sofas - Prevent Scratches on Hardwood & Tile Floors

Absolutely great! Works perfectly for the spherical casters that have gone wonky on my kitchen chairs, leaving black marks all over my floor. There's a learning curve with sliding the chairs so the caster cups don't shoot out, but that's a small issue. Loving them so far. The shipping was a bit slow and quite expensive but well worth it, in my opinion.As advertised. Shipping was high but they did come from the UK.
