We sell many thousands of sets of Wine Bottle Tags. They are made from a thick and very durable plastic. One side has an imprint of a grape bunch and our name. One side is green in color for white wines and the other is red for you guessed it, red wines. Each set has a dry erasable pen type marker. You can use them indefinitely and change the wine descriptions on the wine tags many times. They just won't wear out! They are of the highest quality and as with all our products we offer them to our customers at great prices. The Wine Bottle Tag sets make wonderful gifts for any wine hobbyist.
