I was worried maybe this backpack wouldn’t last us the school year. I was pleasantly surprised as we are nearing the end of the year. It’s the most adorable pink and purple bag! It is on the smaller side but we’ve still been able to fit a normal sized folder in it plus her extra clothes and snacks with some room still.

VERY NICE BUT TOO BIG

Size: One Size, Color: Lilac Ditsy Floral

Let me start by saying its a great product and looked to be made very well. I did have to return it though because it was far too big for my child. Other than size being 1 size fits all with no dimensions given and, yes, somewhat smaller than other backpacks (for adults) it seemed to be a decent backpack. Too bad we couldn't use it but if you have a older kid would would great for.

Good Quality

Size: One Size, Color: Light Pink

Bought this for my 2 year old daughter for daycare. Big enough to fit her blanket, diapers wipes and extra clothing. Good quality and fits her well. She loves it.
