They come tied with a ribbon, ready to be given as a gift.
Each coaster is 4.25" by 4.25", and has been sealed to make it water-resistant. The undersides are fully covered in felt to protect your furniture. They can be easily cleaned with a damp cloth.
Please note that each coaster will only have a section of the pattern displayed, and individual coasters will display a different section of the overall pattern. Therefore no two coasters will be identical.
