Here is a pic of my new 3D Clear Organiser Cube (in Azalea - pretty!), containing two 3 oz Go-Toobs and two 1 oz Go-Toobs. I thought I had some 2 oz, but I guess not. The 3 oz tubes fit comfortably inside the cube (the top of the pink one is partially obscured by the TB label). The cube looks pretty full but it is not quite - I could fit another Go-Toob (of either size) in there, especially if I alternated them top to toe, and/or some other smaller containers, sachets and bottles. But the cube is smaller than what I currently use as my 3-1-1 bag, so it will probably only serve this function for me when I am travelling with checked luggage and don't need all my liquids to be in my carry-on luggage.
