This thick hard plastic box of superior quality 11.5 * 12.5 * 24cm with two side slits. I use to store mobile chargers ... putting in an extension cord and power strip all loads in a nod. By cons, if you want to connect an extension cable with integrated power strip with power saw, take his sister because it will be too small (I took the bigger picture for the computer ... and really this is the best! Adapter comp, live socket box, printer cables and computer ... more extension block with more seeing nothing drags) Only complaint: the price from where the 4 stars. RAS still fast delivery.
