3PC Non-Slip Flexible Tool Tray, Large Tool Storage Set, Accessories Organizer, Silicon Tool Holder Mats, Organizer for Screw, Bolts, Washers, Nuts and Small Tools & Accessories.

I feel like these are a good alternative to magnetic trays if you're trying to avoid picking up metal shavings and debris. The grippiness lets them stick to fenders and uneven surfaces easily. Has a lot of little nooks and crannies for storing parts and tools. The holes for 1/4" drive bits are a nice touch, if not terribly useful for my intended usage on cars. The downside to these flexible trays is that... well they're kind of saggy by virtue of the material they're made of, obviously. You need two hands to pick them up when they're full, otherwise they just collapse since they have no real structural integrity to them. Some people love em, some hate em. Anyway, I feel they're a good deal for what you get. I wouldn't pay more for Grypmat brand after trying these.

Comes with 3 different size trays.Each tray has grooves to keep tools from rolling too far.The bottom of each tray is smooth but the rubber material does grip. The 2 small trays fit in the larger tray to save space. The trays are flexible as expected but maybe a little too flexible where if there is a dip where you place it, the tray will sag down till it lands on something.Easy to clean due to the smooth surface. Good way to keep dirty tools from rolling around or making other surround objects dirty when in a car or wherever.There are no hooks, so you can't hang the trays when not in use.
