GSD head tilt. This listing is for an individual coaster. Each ceramic coaster is approx 4x4inches with a full cork backing. The top can be surface washed gently with a paper towel, warm water, and mild soap. To order a set please add multiples to your cart. Please note, due to the handmade nature of this product, there may be slight variances from the one you see in the listing. But that just makes it truly unique!
