These are great. Here to buy second set (fist set 3 years ago and problem free. Handles/clips some say they come off - they are designed to come off if you want them to (you need to intend this they dont just fall off) so that the parts (bottom and top) can lie flat if used separately. They just clip right back on firmly if you want them to be used to clip boxes shut. I am using a bottom part (with clips off) as organiser in kitchen junk drawer. I have used the smaller orange inserts in desk drawers for small stationary stuff. I am using a couple as intended for screws/nails/bolts/curtain fixings etc etc and they are brilliant. Sturdy, long lasting and the removable top shelves mean there is a real variety of size of space to store things including larger lower space or the whole box if inserts removed. They are not a full 'tool box' as not big enough for eg hammers, long screw drivers etc (one of the photos cheekily shows a hammer next to the box). Love them. Well thought out design.
