The ever popular Thinkbaby Bento Box. One of the most sought after items in our feeding set. The Bento features easy to clasp sides which form an air-tight seal. So it's perfect for any type of food or liquid. We have heard from many pre-schools that the Bento is great because it is easy for little kids to open and close it. The product is made free of bisphenol-A (BPA), phthalates, melamine, PET, PS, copolyester, and biologically harmful chemicals. The exterior of the product is made from polypropylene (PP). The interior is made from 304 stainless steel (18/8). The interior of the lid also has a silicone band which helps prevent leakages. Due to the construction the product is highly sustainable. The Bento Box has a wide list of uses whether it's for kids, parents or folks on the go. The Bento box is available in multiple colours.
