Inspire Essential Oil Heatable Bags makes all kinds of bag like items from reusable grocery bags to money purses. Definitely worth a look if you in the area! I will be purchasing more in the future for school. Super simple to wash them too, just put them in the next wash cycle. I find the containers are very tedious. Takes a long time for them to dry because of all the crevasses, let alone washing them 5 days a week, gets tiresome. 4 containers per lunch can = 12 tops and bottoms per day. Sometimes I get away with reusing some that had dry goods inside like crackers or pretzels.
Anyways, not really wanting to rant, lol. This bag here is my favourite. It makes me think of my daughter Alaina.
