The thermos bottle by BODUM, if you're a man, I'm sure you wouldn't take it out for travel. But to be honest, giving this "lipstick" as a gift to your girlfriend is absolutely a good idea.
This thermos looks just like a lipstick. A design with the same shape from 1983 was made of plastic, while inside was glassware. Now, this thermos has been redesigned, changing the material to durable double-layer vacuum stainless steel, which can keep warmth for up to 6 hours, and is priced at $29.95.
