4"x21x1/4" Side Splash  Condition is New. Shipped with USPS Priority Mail.

Unsure of the brand, scratch test indicates marble vs granite or quartz. Appears to be "burleywood" style but also close to "wheat".  Have a several of  these and can send pics of the them so you get exactly the one you desire.  Can safely fit about 4 of them to one large gameboard style flat rate box if looking for multiple.
