The small ones like that aren’t worth it. Too many small openings. I will say my 1st grader has one of the larger ones and it fits wayyy more food (space for a whole sandwich) and she’s big enough now to open and close it without help. I got suckered into the cute patterns with the smaller one when she was a toddler and it was absolutely not necessary.
