The mat is fully handmade.
It works with rubber/metal ball or optical mouse types.

The top layer is made of water-stain proof 1st class quality leather. The proofing is given by the top grain finishing of the leather itself, which naturally repels water.
The bottom layer which sits on your desk is made of fine suede leather, which provides a good grip on the below surface not allowing the mat to slip.

The mat has a vintage/luxury look to it. It will make a great impression on every executive desk. It will also make a great gift to attach to a new laptop computer. It looks great and it's smooth.
