These are wooden dominos that i got from a supplier then i took them and turned all 8 of them into this domino coaster! It's been sanded down with coarse sand paper then down to medium and finally fine sand paper. Once that was done, i used organic extra virgin coconut oil to condition it and keep from getting dry and cracking. This is also suggested once a month to keep it looking nice. The wood that the dominos are made from are black walnut, maple, and red oak. Its measurements are 5x5 inches. This coaster can be used to set your drinks on or even a jar candle works as well. The domino coaster is ready to be shipped on the next business day and arrives within 3-5 days once payment has been received. Delivery time is longer for international orders. Thanks for looking.
