One of the tricky things about having your friends at your house is the amount of glassware they can go thru! I certainly don’t want my friends drinking out of anyone else’s glass but I also hate seeing them set down their drink and forget about it only to pour another one a few minutes later. cb2 has solved my dilemma with these fantastic little party people glass markers! They are made of silicone and have a little suction cup grip. They are bright and tiny so it is really easy to tell which glass belongs to each guest. They are a great way to keep your washing load to a minimum for only $6.95.
