Is there a larger "black" backpack? Don't laugh, if I'm a 160cm/5"2 adult wanting a small backpack, would this fit my shoulder if I loosen the straps?

Hi dear, Thank you for your question. This backpack is designed for the kids.It is a little small for the adults even loosen the strap.I am so sorry that this black backpack has no large size. We have other similar backpacks for female adults. You could search it if it suits you.The ASIN is B01M6D9MBI. Sincerely, Lynne Vaschy Team

What are the size differences between the small and large green dinosaur bags? The measurements are advertised as the same for both sizes.

I thought there was only one size for this bag. I purchased this for my six year old grandson.

Would this hold an a4 folder?

Hi dear, Thank you for your question! We have two sizes of dinosaur backpacks. You could buy the "Dinosaur-large" which would fit an A4 folder. Hope my answer will help you. VASCHY Team

Would the large 15l dinosaur bag fit me, I am 4ft10?

Yes absolutely. I’m 5 foot 3, medium build and I often end up wearing and carrying my son’s backpack, no problem. Also on the upside there’s nothing overly childlike about the backpack., everything is good quality and normal sized (zips, pockets etc).
