Getting a bit off topic here because I haven't actually bought this, but I wish I'd known about it back when my son was small. When we lived in Nevada I'd clean our church early every Friday morning and bring him with me. He always brought his little metal Spider Man lunch box, filled with Matchbox cars. He had plenty of room to play with them on the altar and in the aisles. He was so adorable!
(Now I'm getting sniffly.)
If I'd seen this back then I definitely would have gotten him one.
