These 500ml Manna thermoses are amazing. They keep contents warm for 12 hours or cold for 24 hours. They don’t leak and look great. The slim shape fits in most water bottle holders, whether on your backpack or in your car, and the narrow neck reduces spillage.
Normally, they retail for $29.99, but I got a deal. With a Loops & Lattes logo, they are only $24.95 + tax.
