LASER Precision Carved Coffee Cup Wooden Coaster Set of 4 (Coffee Cup)

I bought these coasters for a friend who is in grad school for chemistry. Other coasters I looked at had the same few elements, either the radioactive ones or the noble gases. Meh. These elements are relatively new additions to the periodic table, so they aren't mainstream or well-known yet. This is perfect for a friend who knows a TON about chemistry already! I also love that they are made of wood instead of plastic because it is more durable and easier to clean, plus they look more elegant. Definitely made for a nice gift and the price was good too!
