Review on True Zoo Wine Glass Markers: Vibrant Silicone Drink Markers for Fun Cocktail Accessories by Nick Andep

They work well and I appreciate that they are made for thicker glassware (I use them for my regular water glasses). They stay in place really well. My only complaint is that some of the colors are VERY similar (they were picked for all citrus, which narrows down the options). For my somewhat color-blind fiancé, this is a deal breaker. For me it's just a little annoying. He can't tell the difference when they sit next to each other. I just think if I were using all of this at a party I would try to remember I had red. Aside from that there are four of these that are red/pink/orange and if I saw one alone I might not be sure if it was THE red one I had.
