Well, the rollers that are commercially available are expensive and very heavy and bulky arch! I would never have thought that such a thing could exist ... A not too big roll and lightweight THAT FILLS WATER (or sand) FOR HIS WORK ROLL!
Extraordinary! I put it in my little greenhouse garden when it is emptied, and when I need it, zouh! I fill and presto, it's gone to flatten everything on our way to him and me! I highly recommend it to gardeners because nowhere else you will find so practical, clever and above all as cheap.
