Do you have a good suggestion for a needle tip bottle? I got one once and it was no good. Leaked around the cap.
10ml Plastic Needle Empty Dropper Bottle
These work really well but aren't the most pocket friendly, it does fine in shirt pocket though. I also have a sample bottle from RAWR that has the longer thinner Dripper tip. I has childproof cap and is pocket friendly, but its a little wider than the one posted above. It can cause an airlock when trying to fill if not careful. Also a lot of people are using the uCan, some have leaks some have no problems.
