How many times have you thought, "Boy! A tiny funnel would make this job so much easier!" Well, we have thought the same thing. This small plastic funnel makes transferring inks from one bottle to another much easier and faster. For ink mixers, you are no longer limited to your dropper. This funnel is about 2.25" in diameter and the spout at its largest section is about 10mm in diameter. Includes three funnels.
