    Micro lite flip

    Lost for words really. A fantastic product, very well made. I would highly recommend this to anyone wanting to have a good quality and reliable product for storing hot and cold liquids in. If anything it’s too efficient at holding hot liquids in. Stays hot for a very long time.
