    I ordered this bamboo thermal flask as a gift. This is the most special thermos I’ve ever seen. The bamboo body of the bottle is already a feature, and it can also be engraved with any desired content. It is a very personalize thermos that I no longer worry about mixing with other people’s thermos. Wow!!!!
