Cleaning up is never been easier. Stack blocks on top of each other, it will take a small space as a tower in the corner or wall against the wall. Those days are over when you had to pick up small building block parts in every corner in the house, cleaning out blocks from vacuum cleaner or even worse, step on them. And neutral color will fit in every interior.
Look at pictures here, how compact GIGI Bloks can become after playtime.
By the way, if you are interested, how much times you can fold and unfold blocks, we suggest not to go above 8 times. Up to that, they will be fit.
The only difference is in size.
XL is 60% from XXL block size.
XXL are 7.87x3.94x3.94in (20x10x10cm).
XL are 5.11x2.56x2.56in (13x6.5x6.5cm).
