It's quite easy to assemble and holds up to five boxes of max weight stacked on top. Doesn't tear or rip when pulling from shelf via the hand hold. Worth the extra $ for the stronger box.
These boxes fit great into the selving units I use in my business. I purchase mostly used toys and need to sort a large quantity and either give them away or sell them. These boxes are fantastic for their sturdiness size and ease in moving. The only problem is the price jumped from last year. But so has everything else!!.
