Aside from transporting heavy items, it turns out that wooden crates can also be a mug mat as is the case with the Wooden Pallet Coasters.
Etsy user Christopherh designed the Wooden Pallet Coasters which is a set of wooden crates that have been miniaturized to a reasonable size for mugs. These are made from reclaimed lumber, so there's a nice eco-friendly aesthetic to them for those leaning towards a greener lifestyle. The coasters were put together with a waterproof glue with a semi-gloss clear coat finish. Four miniature legs with soft felt pads attached have also been added to keep the table from being scratched.
The natural aesthetic of the Wooden Pallet Coasters will beautifully complement any home looking for something different.
