How to use a straw to store squeezable semi-liquids?

Here's a video that might help.

I use those boba straws to store some triple antibiotics plus other items as well.

I bought some flowers recently and they had large, clear "straws" around the stems to prevent them from dropping. About twice the diameter of normal straws, they could be used for larger volumes.

So buy your sweetie some flowers. Or flirt with a florist. Which may result in a different outcome.

Have you thought about these small poly containers?

There are multiple sizes (up to 2 oz, I think). They just seem easier to use.

Those flip-top polyethylene containers are handy and cheap but are a lot bigger than the soda straw option (1.8 x 0.6 inches) Also, while I'd trust them with semi-solids like stick deodorant or vasoline-soaked cotton balls, the lids are not liquid-tight in my experience.

For sunscreen, DEET lotion, and other viscous liquids I use little polyethylene squeeze tubes like these:

Last time I looked for these, I found them in 5 ml capacity (1/6 oz), but the smallest I see right now (in a cursory internet search) are 10 ml (1/3 oz):

The tips on mine are little domes with a tiny hole at the vertex, and the threaded cap seals against the hole so they don't leak. The tubes being sold at the link above have slightly different caps (angled tips, not domed), so I can't testify to those (but they don't look like they'd seal quite as well). With some searching you could probably find some with domed tips that seal well.

Colin: Nice find! They also have a 3 ml "dispenser tube" and a matching filling syringe. Since the dermatologist moved out of my wife's medical office my source of many, tiny, professional samples has dried up. Also nice is that they offer USPS shipping to Alaska, so I just ordered up some of their smaller options.

David, just a word of caution: the mini atomizer bottles ("misters") at Lotioncrafter are crappy. I bought some of the 8ml size for bug spray and all of them broke after a few spritzes.
