The Big Frig Tumbler is a great thermos mug, whatever size you choose. But it may happen that you simply lose or break the sliding lid that is included in the package. That's why the manufacturer offers the option of buying a spare lid so that coffee doesn't spill on your pants or a fly doesn't drown in it.
In this case, it is a high-quality lid with a sliding closure for drinking, which is intended for a smaller version of the Big Frig Tumbler thermo mug, i.e. Tumbler 20oz (approx. 568 ml). Only with an original thermos mug will you be sure that the lid will fit exactly on it and will seal perfectly. Not only will the drink not be spilled sideways, but it will also not eliminate the insulating properties of the mug. And what's more, it does not contain harmful bisphenol A (it is therefore BPA Free).
