I have been using these boxes for several years. I got them at Harbor Freight. Sometimes you can find them on sale or use a percentage off coupon. At $4.99 they are pretty cheap.
Having them in individual boxes sure helps if you drop the main box.
Each little box has plenty of room for any bushings.
I cut the name of the bushing off the bag and put it in the box.
I have three boxes and lable the main box A, B, C and then number each little box 1 -24. So, a Sierra bushing set might be in B17. I then have a spread sheet for each box with the bushing description (pen name, etc), the vendor name, and the part no.
Sure is easy and quick to find a bushing.
