I got these because my previous one from a different brand, the silicone is so thin you can actually see through the folds. These two though are much thicker and more durable. One is black and has a squared off end; the yellow one has a very small rounded tip. My husband uses a CPAP machine and uses a funnel to pour the water into the tank. It is also great for pouring drink mixes into small-mouthed containers. I also use them for refilling my #cooking spices into their little glass bottles. The other one I keep with my lantern oil and lanterns. I wanted one so it could stay with the oil all the time and be designated as not for food use. Lanterns can be difficult to pour oil into so having one of these little guys is ideal.
These are FDA-approved, BPA free, and of course #food safe. They're supposed to be heat resistant but personally I haven't used them for anything that would expose them to a very hot temperature. I wash them by hand but they are dishwasher safe. I am sure one of these days I will be too tired or lazy to do it by hand and I'm glad to know I can just pop it into the dishwasher and not worry about it. I definitely recommend this two pack because there are so many uses and they simply don't take up hardly any space at all. http://www.amazon.com/gp/product/B07GVSQQ3G
