Hinoki Kumiki Trivet Prison Correctional Work Product Cypress Wooden Hinoki Scent

Purchased at a prison correctional exhibition in November 2025, but I am listing it as I have no opportunity to use it.
This is a cypress wood interlocking trivet.
It is used by fitting two pieces of wood together.
It is solidly made.
When not in use, it can be disassembled for compact storage and hung up.
It is chamfered, carefully crafted, and a warm piece. The wood grain has character.
Used a few times, there are some minor scratches.
Size per piece of wood:
Length: 20 cm
Width: 4 cm
Thickness: 3 cm
*Price negotiation is not possible.
This is a home-stored item, so we would appreciate it if you would purchase it with your understanding.
