Each mat has a 9 1/2” diameter and appears to be made of a thin wooden octagon with a decal attached.  Per the packaging, the surface of each mat will resist grease, fruit juice acid, and alcohol.  The mats can be wiped with a damp cloth and liquid wax polish can be used to keep the surface bright…..the mats should not be immersed in water.  The table mats are resistant to heat, but are NOT heat proof.  Dishes taken from the oven should NOT be placed directly on the mats.  These lovely mats come in the original sealed package…..the back has large creases in one corner.  Buyer pays selected shipping.
