I travel to Third World countries a lot. And I hate all the plastic water bottles that are needed. I like to buy a huge jug and fill everyone’s water bottle so that we aren’t putting so much plastic into the environment. This collapsible funnel is perfect. It has a smaller opening to fit your water bottle. And it collapses and takes up very little room in your backpack.Mine came in a package that was completely taped up. Definitely didn't expect to pay $7 for a funnel that had been opened.This funnel is great for liquids since it is very big at the top and becomes very small at the bottom. Additionally, it folds up for easy storage. The silicone also allows the trip of the funnel to be wrapped around something and not leak, still forming a watertight seal even when it does not fit exactly the container you are pouring into.This a really great size funnel and fits containers with very small openings- as small as 5/8 of an inch. I purchased it to use for mixing up my own cleaning products. I like that it folds up so I can pop it into a drawer.I searched for the perfect silicon funnel for my Kombucha making. This is thick and high quality and molded perfectly.great! only problem is if using with powder, which my husband does for his workout drink..it can stick on the rubber..a metal one might be best for things like that!I love all my kitchen products that are made of silicon and flatten for easy storage. This is a great addition to my collectiongood funnel
