2 in 1 Prep Funnel 5 "Incredibly useful" 02 July 2015 I bought this funnel to use the 2 combined parts simply to pour liquids into bottles. Once I started using it, I realized it's amazingly versatile, both with the 2 parts combined and also separately. The small, narrow-ended, bottom part is ideal for narrow necked bottles such as for my handsoap. The top part I use alone for powders (like coffee). For the coffee it's the only thing I have which enables me to get the powder into my wide-topped jars without spilling any. I also use the wide, top, section with a strainer lodged inside; it really does stop any splashing.
