barrels (and not from factorization)

[elkillo]

im using the direwolf20 pack and i've notice in NEI there is a liquid storage item by the name of the barrel. i can craft them but i have no idea what they do or even which mod adds them.

They're from denoflions' Plugins for Forestry mod. I *think* they hold 10 buckets worth of liquid? not entirely sure on that amount
