This one works perfectly when making home remedy capsules out of powdered substances - a couple taps clears the funnel and adds the powder to the capsule, making fills a breeze that hardly even need a supplementary brushing.

Arrived safely, packaged in a small box with foam padding. Just as described. The stem is small and tiny. The funnel is in need of a small brush to clean it. It is a nice, handy tool.

I bought this funnel because the questions and comments pf the "best seller" were not correct. This one fits my O capsules just fine and probably fits at least size 1& 2, and maybe smaller. The stem is sturdy for it's size, ut you still need to handle with care.
