Thank you for viewing. This is a 3COINS antibacterial cutting board set. Originally a set of 3, I used one, so it's now a set of 2. Therefore, it has been opened, but it is new and unused. The thickness is quite thin, about 1mm or less. Because it's thin, it's easy to store, carry around, and use outdoors. There's a round hole on the edge, so you can hang it on a hook for storage. Also, I don't smoke. I don't have any pets. Shipping included, and will be sent via anonymous delivery. Thank you.
