Review: original and good quality - all good Review: Great Screws and Nuts, terrible separator design - Screws and nuts are great quality otherwise I would have gave this 1 star just for the container, you would expect a product like this with variety screws would have proper separators. The separators for the container are absolutely flimsy. They wiggle and move around and once a screw or nut finds its way underneath the separator the container will no longer close. Why would they make movable separators like this is beyond me and bad design. Absolute nightmare to get everything in place. ## Features - 1.
