I was at a party two weeks ago and lost my drink three times…we were all using the same cups and I kept forgetting where I put it…if we had been using etch-it cups, this would not have happened! They might cost a little more than plain cups, but you will end up saving money because people will only use one cup instead of ten! Each disposable cup has a label that you can sketch your name into…they are fun for kids and adults. You can buy them online at Giftaria.com by the package or the case. They also sell labels to turn any cup into an etch-it cup.
