Coffee sleeves were probably one of the most brilliant inventions ever conceived. The 'Caffeinating Please Wait' coffee sleeve helps to keep your coffee cozy and humorously let people around you know that you aren't ready to properly function until you've received a full coffee charge.
To many people, coffee is the body's power source. It's only fitting then that this coffee sleeve is designed to look like charging battery. Between the "caffeinating please wait" text is an embroidery of a tiny rectangle that is filled 3/4 of the way with blue to indicate the charge your body is receiving from your cup of coffee. Not only do they keep java warmer, they also protect our finger tips from getting burned.
No cup of on-the-go coffee is complete without one of these caffeinating coffee sleeves.
