Finding a quality funnel for oil painting mediums was damn near impossible. Finding a quality small sized funnel was a chore. This little dude is the solution. Now it is not indestructible! But I've have dropped it a few times on my tile floor and somehow it did not break. But I'm not pressing my luck because it is glass! Some of the oil mediums (mixtures of my design) will discolor and likely cross-contaminate plastic funnels and (I also fear) saturate the plastic (making them even more flammable than normal). So glass was the only way to go!

Fits perfectly into my 00 size capsules. Very happy with it.

Item arrive on time and in a safe package.
If you're irdering this item based off the image, be warned that the tip is not as thin/small as the image shown. I understand that the description says what size it is....but if you have no experience with these items, you have no clue what those dimesnsion mean. A more accurate image would be helpful to other buyers.
I ordered this to fill size 5 medicine capsules, the smallest you can find; this funnel is of no use, as it is too big for the capsule.

I used this funnel to make my lip balms and am reviewing off of that use only. Do not buy this for that use because the wax, among other products I use, get clogged in the tip. More product got stuck and clogged than what went into the snort chap stick tubes. Complete waste of products, time and money. I'm sure this funnel works great if you only use it with thin liquids.
UPDATE:
I found a new use for this little guy; I make my own essential oil rollerbottles in 10ml amber bottles. This is perfect for adding a carrier oil into the bottle. Just perfect!

I bought it to use as a wire mold to make a merkabah shape. 50 mm is very small. It will be useful for transferring essences/extracts for example Frankincense, that I use often. It is not useful as a wire twisting mold, although it is tough (I did not break it yet). About big enough to put all of a woman's five fingers inside, smaller than a cocktail glass same shape and might be useful for holding a sphere on top of a pyramid by using the stem as a shaft to pierce a top ball which is then sealed with hot glue. If I clamp it it might break using 14 AWG and smaller wire won't stay either. I'll get a bigger funnel for molding wire into a cone.
