for sort out screw -lrb- different size -rrb- , nail , wire nut , bit , bolt , rivet or anything you have lay around the house loose . I have 3 of these and they be perfect for what they do . though kind of heavy when full , they have the strap in the middle which make they easier to carry and a loose string to pull to tighten they up when there not that full . for the Handyman , they be excellent to have . you can store just about anything in they . you will appreciate the bucket boss !
