I'm sorry, I didn't see the reply notification! I use Addipak: https://www.amazon.com/ADDIPAK-Unit-Dose-Solutions-3ml/dp/B00XCQXPMY

The ones I get are in the skinny pink plastic, but don't be dismayed by the amount in the vial - the 5ml is "full" and the 3ml is "half full" (like the skinny green one). People in the comments who don't read how much they are getting or what the vials are marked as complain that they get 'ripped off' when the vials aren't full.

I have a bunch of the 5ml, but I end up only using about a quarter of it at a time. I pinch a piece of washi tape over the tip and leave it on my desk to use the next day. You can't re-seal them after you twist the end off, but if you don't squeeze them, they really won't leak.

Hope that helps!

Here's what my doctor recommended, I've been able to fit these in my pocket on the go - https://www.amazon.com/ADDIPAK-Unit-Dose-Solutions-3ml/dp/B00XCQXPMY/ref=sr_1_3?crid=2RV29710OS9MP&keywords=addipak+unit+dose+solutions+-+5ml+100+ea+box&qid=1647548993&sprefix=addipack%2Caps%2C136&sr=8-3
