Tip: A wooden Mancala board makes a great sorting tray!
A Mancala board is the best for sorting screws.
The wooden concave holes makes it easy to pickup screws and small parts when repairing laptops and phones.
They come flat or they fold if you want to save space. You can new get one from Target for about $13.00 or get one at a garage sale, flea markets or craigslist for cheap. The last one I got cost me 75 cents at the San Diego swap meet. There are millions of these out there collecting dust, recycle them into a great work bench tool
