I was looking to buy custom koozies to market for a new client and found a great site expressimprint.com which let me design them online. Really cool sites to get koozies that are made in the USA! They sent me a bunch of samples to choose which one I wanted, Can’t wait until my custom printed ones arrive in the mail next week. Now is the hard part, which one should I get? After finding out which ones do work I will make my decision.
