Sometimes we print the occasional koozie or coozie, it's your call on that one, it's not our bread and butter but it's a fun little break from shirts.
Today we printed several koozies for a group called Engage the Current (http://engagethecurrent.org)
Here's a look at them.
Koozies make a great promotional item, but sometimes they are forgotten in the light of stickers or other typical giveaway items. We have printed for several small businesses that like to add in a bunch of koozies with their shirt orders as giveaways with purchases. In fact a great customer of ours Rawkworks does just that, with each guitar pedal he sells he tosses in a koozie with his logo and website on it. It really is an underrated form of promotion that doesn't typically cost all the much to make.
Next time think about adding a few of these guys to your order and using them to spread the word about your business.
