I've been using the Adam's funnel for a long time to help in filling up my 32oz bottles faster & also to keep from spilling chemicals all over the place.
I finally bought some to sell in the store. The funnel will fit most 32oz, 16oz, 12oz, 8oz, & 4oz bottles with ease. These are cheap enough that you should buy at least two of them to have on hand.
