This set of anatomical image coasters are perfect for the health professional, med student or anyone interested in anatomy.They are created using a base of rough and rustic stone travertine tiles. Each coaster measures approximately four inches square and has been fully backed with cork for a steady and secure footing on your furniture.Each coaster features vintage anatomical images overlayed on top of antique script. The images have been applied in a transparent medium to allow the color and texture of the natural stone to show it's character. The coasters have been well sealed to ensure durability. They can be used with both hot and cold beverages.The coasters offer a unique and eye catching way to display some small works of art in your home. Each collection is lovingly created and attention to detail is of the utmost concern. I wanted to make a collection of rich and warm home decor... useful items featuring inspiring and beautiful pieces that you'll be proud to own and display for years to come.Coasters can be wiped clean with a damp cloth... they are not dishwasher safe.
