Our product comes with 4 coasters and 1 holder. The coaster are 3-3/4"(w) x 3-3/4"(h) and are made of Bamboo. Bamboo does not engrave evenly but it comes out with so much character making each engraving one of a kind. Bambo cleans very easy and makes a great gift for a stocking stuffer, for a work gift and even for a wedding gift. we currently have 1 design but if you email us before ordering we can definitely make it to your liking and we might even and to the design option. If any issue comes up please let us fix it to give you the best customer service we can.
