The product is fine, yet it keeps anyway. The size is a little big for small kindergarten bags, but ideal for backpacks and school bags. Only thing that really annoys me is that I paid more than the MSRP. Which is namely 5.95. Why are sold through Amazon products which are more expensive than the price from the manufacturer. Here I have only 1 paid more at another Lillifee lunchbox that I ordered at the same time, I paid 2.30 more. When I wanted to send them back, was also here a hook ... because the shipping costs for returning are at 3.50. Since the product was indeed not broken and the value is not more than 40 lay, the shipping by the buyer must be paid. So a return is not worth. In the future I will be more vigilant for the price comparison.
