SMALL ONE: "approximately" 13 1/2" W x 7" H x 6 3/4" D. Holds approximately two and a half to three (2.5 - 3) gallons of water - "assuming" the seal is still good.
LARGE ONE: "approximately" 19 1/2" W x 13" H x 7 1/4" D. Holds approximately TEN (10) gallons of water, "assuming" the seal is still good.
Buy either or both.
$25 for both.
OR,
$15 for the bigger
$8 for the smallest.
Both are used. I'll clean out whats in them, but you'll have to wash them out. Didn't leak when last used, but unsure about now. If not good for fish/water holding, then some other sort of dry use - pets. Snakes, frogs, lizards, etc...
