Perfect for parties!
I received this product at a discount in exchange for my honest review.  These markers are so extremely helpful during parties!  We not only use it on wine glasses, we use it drink glasses and beer bottles as well.  We love the bright and metallic colors.  Some of our visitors even created their own art work on the bottles.  Another plus is that it came in its own case, which doubles as an eraser.  Clean-up was easy on our drink glasses.  Some of our major jar mugs, it took a little bit of elbow grease to get them out, which is the reason for the 4-stars instead of 5-stars.
