This gift is perfect for someone who throws lots of parties, or entertains a lot! Drink Duets from Cheerware are customizable party ID tags. They have ID tags for water bottles and wine glasses. Whenever I have parties, I always leave out a sharpie for water bottles, but often times the sharpie gets lost, or you can’t write on the bottle if there’s too much condensation. Drink Duets comes with foam letters that guests can use to customize their tags (if they wish), making it much easier to find your drink! Wine charms have become a popular gift over the last few years, but I am in love with the Drink Duets ID tags since you get more ID tags for your money, and they have the water bottle ID tag option!
