We've carried out several tests on the Air Gifts thermo mugs and we have no doubt: they are leakproof, thermal insulated and perfect for single hand operation! Such great products deserve your logo. Check out how we tested them:

Recently our tests got a lot of attention. We took several Air Gifts mugs from the stock, recorded our tests, and put them on the web.
"I didn't know they were so pretty", "it's really leakproof" or "they really don't leak", "oh, they have such cool packaging" - these are the most common comments on our latest video.
We invite everyone to watch them! Air Gifts thermal mugs tests>>
