We recently scaled up our Evans Dual rock tumbler to hold an extra large barrel. You can shop for these through our rock tumbler page. This new purchase means that we have three small 2.5lbs rubber barrels sitting in the cupboard doing nothing. 
 
While it is entirely likely that we will buy another rock tumbler which can use these barrels, we really don't need three of them, so this one is for sale.
 
This is the newest barrel, maybe a year old. We use these on rotation of three so it hasn't been that badly worn at all. It features the lid with the hatch marks on it, which the old hobby tumblers from Nat Geo don't have. 
 
Although these can hold up to 2.5lbs we like the bigger barrel which as more space for the same amount. You want your rocks to be able to move about in there. Give em space.
 
You can read more about what to look for in a beginner's rock tumbler on our blog and we also have some newly added instructions on how to tumble rocks, should you need them.
 
This rock tumbler barrel is about 9 and a bit centimeters tall. Please measure your machine to make sure it fits before you order to avoid dissapointment.
