Does any one know if I'm able to use this on the big tub instead of the can?

does it say anything in the small print?

Cant really see what it says in the fine print to tell or not

@amber.s95 @leiibaaaby this is what is says

plus the back, I guess I can use it

Yes you can it has no size restrictions 👏👏

since it doesn't specify a size I would think you could use it on one
