We have both the original and panino size and the panino has won out as the favorite because it seems to fit my kids' food preferences best. You can fit a whole crustless sandwich, a small wrap cut in half, or a few silicone muffins liners with homemade lunchable type items in the large space. The other 2 compartments will hold a decent amount of fruit/veg/yogurt. We use the small spot in the middle for a tiny sweet treat. Our son has used this size from Kinder-2nd and it is still in great condition. We will be getting the next size up.
