This coffee carrier makes it near impossible to spill your coffee. It is designed to fit almost all coffee mugs. The centered hole, and attachment of a string makes this very hard to spill using principles from physics.
Secure a hair tie or string through the hole in the top to carry it with.
--Profitability Breakdown ($9/hr) --
Coffee Carriers like these sell for around $18 on Amazon and seem to sell very well. But this model allows you to print and sell them on other sites like Etsy
