Small thermometer for travel case?

[Blackcat99]

Can anyone recommend a really small thermometer to put inside a MediFlask travel cooler flask(USB charger). Ordered last week and it has just arrived - seems a well-made item but, surprisingly, doesn’t have a built-in thermometer to allow me to monitor temperature while travelling. There’s very little spare room inside alongside freezer gel pack plus 2 teriparatide pens, and I can’t seem to find anything suitable online.

Weirdly, the more basic travel case that I bought for shorter journeys has a built-in thermometer with outside display - and it cost less than 20% of the much fancier item!

I see that someone has saved my post (above) so assume they may be looking for something similar? After wasting hours searching online, I finally found an ideal thermometer in the local hardware (aka Aladdin’s Cave!)

ChefAid fridge/freezer thermometer 11 x 2 cm x 1cm deep. Cost all of £4.99. It doesn’t have an alarm, but fits very easily down the cooler flask at the side of teriparatide device, will try to attach photo!
