Kikkerland set of 4 puzzle-piece drinks coasters

Set of 4 brushed stainless steel (not labeled but pretty sure that’s what they’re made of) drinks coasters. They look like puzzle pieces, and actually fit together (see photos). Backs have non-slip plastic bubbles I have two sets of 4, listed separately. I’ll offer a better price for all 8. Color: Silver Material: Brushed Stainless Measurements: approximately 4.5” X 4.5” Condition: brand new, never used I love offers! Questions welcome! Smoke free environment
