Hi there,
Neither of those boxes are big enough really, you are better getting this one or 2 if you want levels.
Crystal Storage Box with Lid Clear 62ltr at wilko.com
However if sonic is a syrian you wont get a 12 inch whell in there due to the height unless you cut a hole in bottom of top bin for it to sit through.
Mesh you can get from b and q and homebase
Blooma Galvanised Mesh (13x13mm) Panel (H)0.6m x (W)0.9m, 5397007006568

Hope that helps a bit,
Alternatively you could get one big bin, i have this from asda,
