The play area walls of this bag stand up stiffly so as to create a barrier for the child. Holds the perfect amount of legos and hot wheels for travel and is easy for my toddler to carry.

The handles are on the under side which requires it to be very rightly cinched. I just help him tuck the string into the hold after cinching it. The wide casing for the string closure makes it easy to pull shut.

It's very easy to toss blocks onto the mat (or whole creations) and then cinch it up. The way it solves the problem is by putting a little ten centimeter wall around the lego area. This almost solves that problem.

The worst part is that the sides simply don't stay up. Might as well just use a throw blanket instead.

Wish it was a bit sturdier. But the reality is the lids don't actually stay in place when closed and pull right off when i open them. This is just a peace of cardboard that does not hold there one weight!
