Good idea in theory but not in practice

Looked like a good idea to keep all those little drills organized and easily accessible but doesn’t work for the really small ones. From #76 to #80, if I remember correctly, are short enough to get sideways under the lid and get through the gap when the container is tipped over to remove any other drills(the opening is too small to use a tweezers so thats the only way i can see to remove them). Any that don’t spill out completely are under the rotating lid and require removing the top to deal with the mess. I lost some of the smallest drills learning this the hard way. I left the cap off to keep myself from forgetting and recreating the mess.
