These Cork Trivets are perfect for holding hot food items. They can also be used as plant holders or as mini bulletin boards. The cork we use is actually super thick cork flooring. No worries about sticking a pin through the cork. Also, the thick cork slightly extends at the bottom of the board, preventing it from scratching your table. The type of wood used for the frame will vary depending on availability. If you have a specific wood you would like just drop us an email with your request.
