Review on Washable Vino Marker Wine Glass Pens - Ideal for Holiday Parties, Home Bar Accessories, Bachelorette Party Favors, Wine Tasting Decorations or Any Event by Michelle Taylor

Bought to write on glasses and they are great! Colors are as expected, ink holds up. If you touch them with wet hands or rub them with a wet towel, the ink will come off. But other than that it's holding up very well! I use it to write names on mirrors and glasses at parties. Everyone loves her. The only thing to watch out for is that some colors are better for some things than others (e.g. gold doesn't show up when you write on a glass full of white rice or a glass of white wine, it's great). for a glass of black beans or red wine).
