Mine is a plastic milk crate. Dirt falls thro the bottom plus it holds plenty.
This is a good idea, only with they had a handle for one handed carrying. I am also in the market for a larger container for my grooming supplies. This will make number three. I keep going up in sizes.
I have a couple of Duratote and Fortiflex boxes and love them, they do hold a lot. I also have a couple of totes that I like. The Duratote and Fortiflex boxes hold more stuff and are easier to clean out than the tote bags. The tote bags are easier to carry if you have your hands full, you can just hang them over your arm, and you can also hang up off the ground on hooks. I like both styles!
The Duratote with the step stool cover is a great idea, especially if you have tall horses, like I do, also, the step stool cover keeps the stuff in the tote clean when you aren't using it.
Tote :) It seems so much more organized, but a bag does the same job when you think about it and you can hang it up anywhere! I really like MFfoundation Qaurters idea about rolling tool boxes, maybe one for the tack room and another for the trailer!
