- The Grinder is an object, also called yo-yo or grass mill, used to grind, to crumble the grass saving the effort of crumbling it by hand.
- there are several quality, color and size.
The Grinders with sieve, are like the classic grinders, small mills, but equipped with a compartment in which is fixed a small grid with the very fine mesh which will allow to recover the resin which is detached from flowers when one uses the grinder.
there are wooden grinders, aluminum grinders and other types of grinders plastic.
We recommend quality grinders because the cheap ones from China leave residues once the grass is ground.
