What size (diameter) is the neck?

Hi, Kenney. In the reviews below, David Gailes entered some specifications for this item, and he put the neck diameter at 1/4 inch externally, 1/8 inch internally (ie, the exit hole would only be 1/8 inch). I don't have very precise measuring tools on hand, I'm afraid -- in fact, I only have an old and rather beat-up wooden ruler -- but from what I can discern using that ruler, Mr. Gailes' measurements look good to me.

I need a small metal or glass funnel to fill (pill) capsules size 00. Would this work for me? Thank you!!

The outside diameter of the stem is 6 mm so it should fit into the 00 capsule which has an inside diameter of approximately 8 mm. However, the bevel on the stem is >7 mm so I don't know how much material you can deliver into the capsule. One option might be to cut the bevel off to flush.

Where are these manufactured? Trying to avoid China...

This item is manufactured in China.

What is the ID and OD of the stem of the funnel?

Great item. For Diy e juice, stem Just to thick for normal 30ml Bottles (plastic). works for glass and unicorn Boyles great in 30ml, Also any other bigger bottle sizes. Was not protected that well during shipment. Wasn't broke so no big one

Love this tiny funnel - It's about the size of a pop socket in diameter at its widest, and the neck is thinner than a Starbucks tall straw. So useful for working with essential oils and not making a huge mess.

I should have bought more than one, this great little funnel works fine to help me fill my graduated cylinder's so I don't spill my aquarium additives. It came well packaged to prevent it from being damaged and arrived ahead of the delivery estimated date. Thank you!

Good glass. Well packaged. Works as intended. Good for dispensing corrosives.

Much smaller then I had expected I guess I should pay more attention when I'm ordering my only complaint is that the steam was poorly cut and required me to re cut and heat to take the edges off
