Magnetic Parts Tray is great for ecigarette Rebuildable Atomizers (RBA). I think having one is a great time saver for vapers. Other cool ecig accessories I posted about before are the vape stands and ecig mod polish.
I use this because it helps prevent spending so much time looking at my floor for metal screws for RBAs when rebuilding. It comes with 3 trays. One is for rebuilding at home the other is in my rebuilding box, and I gave one to a buddy.
You can get them through my amazon ecig store here under ecig assories or click here Magnetic Parts Tray
