Wow! These are lovely. They’re slightly rectangular at the top so they can be “mashed into” spaces that are square. They were bought to match storage baskets. Dino constellation style. We had been using a 13x13 cube for our toddler LEGOS and then I got another big box of Duplos and put them all into a nice clear storage box with those flip tops that fit together like a puzzle.THIS makes LEGO cleanup take maybe three minutes with two toddlers (4 and 2). It saved my sanity. Lay it on its side and shove 70% of the Duplos in it with your toddlers, set it upright, and pour several armloads in. Done!!!!!!!These really are a great size and shape. People who complain don’t read that you can use a blow dryer to get the wrinkles out. I have ZERO issue with my pair. It’s a good size. I’d say you could hold four yoga mats in it and not see the ends poking out.Probably two pillows, a twin sheet set, and comforter would fit in one of them, or ten basketballs, to give everyone an idea of capacity.I have the 3-pk of dino constellation baskets as well. The baskets each fit winter boots, rain boots, and at least a dozen pairs of toddler size 11/12 shoes, and are the PERFECT fit for our bookcase. Those dumb 11x11 and 13x13 cubes are not the best size for many things.I love this hamper, it’s easy for me to carry around and do my baby’s laundry and it’s also sturdy! Highly recommendJust the right size for small laundry or storage. I use one for laundry and another to store an extra pillow and light blanket in spare bedroom.It has many many uses and it’s made of sturdy fabricI wish it was a little thicker and wasn't so easy to misshapen but it stands up and doesn't tip over. It's easy to shape without steaming.I love this hamper. It is very strong. The material is thick, and it collapses. It’s great.It nice but it too soft I just got it recently and I'm not sure if it would last long once the baby get here and I start using it alot which is why I'm also getting another laundry basket definitely not the same brand.This clothes hamper is cute. But to be honest I was a little disappointed when it came in. It feels cheap. I bought something similar from target for the same price and it is much sturdier. I mainly got this because of the sharks on it. Overall it does the job, just not what I expected.Won’t stand up in its own, horrible quality, ring around the top to keep its shape was folded in half for shipping which wrecked it. Don’t bother buying itmaterial grueso e impermeable, lindo diseño y buenas costuras resistentes. Se aplasta para guardarse y cabe donde sea.Was going to use this as a laundry basket but it doesn’t even stand up properly because it is practically made out of paper. Not worth the money.I'm actually using this for my pet hedgehog, to put all his toys (tunnel, cuddle cup, blankets, etc.). It stays up, not too big yet large enough to fit all his things. Exactly as shown in pictures!Doesn't stay up, very cheaply made.
