These were exactly what I wanted. I have another italian set of animal cutters that are just this size, so I knew they were small. I bought them for bento for lunches and they are perfect for cutting out cheese, lunch meat, carrot slices, apple slices, even mango (I turn them over when partially cut through, and press against the metal cutting edge with my finger, which makes a nice neat cut all the way around). My son will eat a bunch of flowers and butterfly pieces of cucumber, apple and carrot, and they look adorable on a salad, sandwich, or spread across his bento lunch box. I also use the edges of the flowers to cut little notches into slices of meat and fruit to make larger flowers.
I would give a 5, except as others have noted, they will rust if you don't dry them. Wash them all off right away, and toss them in a towel or paper towel and leave them out to dry before putting them away. I have found all metal cutters have this issue, esp small ones.
Oh, and last hint: when cutting out things, use a small skewer, edge of a spoon or whatnot to push out the wee bits so they don't stay stuck in the cutter and tear off when you remove them.
I will be buying more of this size for wee bites, in different shapes. Excellent product.
