I just picked this Maximum waterproof toolbox up at Canadian Tire yesterday. They were 50% off last week, 75 CAD (about 50 USD). The sale ended today though. They are waterproof and lockable. There is egg carton style foam top and bottom with two pickable foam layers in between. I was able to fit my entire Mavic Air 2 Fly More Bundle in it plus my tablet holder. Had I been more careful I could have fit my cell phone, but I’m happy for the price. They also have a smaller and a larger size. These often go on sale for 50% off.
