I purchased a critter lunch box two years ago for my grandson and it's still going strong. They are durable, easy to clean and keep the food fresh until lunch time. Now that our granddaughter is starting pre-school I purchased the pink butterfly Critter Lunch Box for her. She loves it.
I bought this for my daughter who attends a "green" school along with the Kleen Kanteen. Both products do not live up to expectations and they leak! We purchased this product specifically from LL Bean because of the insulation and the plastic lining. However, anything that gets spilled on the inside of this lunch box leaks through the zipper and the seams. I put this upright on my counter after my daughter came home from school. Something had leaked inside the lunchbox and it was in a puddle around the bottom of the lunch box (not a small leak, but a large pool). Beware if you have any kind of stone countertops what you put in this box that might leak out!!
I would return this product in a heartbeat because I feel it really is terrible, however, the hassle and the cost of return shipping are not worth it to me when the product is clearly defective.
