3PCS 5ML Empty Refillable Amber Glass Nasal Spray Bottle Pump Cleanser Container Boxes of Glass for Nasal Spray Saline Water Applications

They work great. A little small for daily use, but otherwise they're wonderful

If you don't need exact measured doses, this should work fine. If you're relying on a tolerance of less than +/- 10% per actuation, these are not for you.I tested twice with 3mL and got right around 30 sprays, but it varied by about 5 between tests. Then I did 5mL and it was around 42 sprays, where I would've expected 50I estimate about 0.1 mL per actuation (0.1 mL/spray), but it's inconsistent, so don't do anything potentially dangerous or where accuracy is important with these.Update: These leak REALLY BADLY. Do not buy, trash

I keep these around the house filled with saline. Good during winter when your sinuses are dry. Work well and has a fine mist.

They aren’t watertight lids, will leak if stored upside down

I guess I didn't read the details close enough, but these were much smaller than I was expecting!

The atomizer straws are to long and you have cut them to get them to work. So basically the sprayer is incompatible with the bottle and to make things worse the bottles leak. Not happy with quality or performance.

This is exactly what I was looking for. Excellent for use in taking microgram dosages nasally. Produces an extremelyfine mist

This was my second order for these bottles. I have a prescription for Ketamine (don't freak, it's the LEGAL Ketamine) and after just two (2) refills, the sprayer clogs beyond repair. Obviously tried hot water and then even rubbing alcohol to no avail. Not even going to push my luck for a third time. Not sure why the reviews are so high! Lousy quality in my opinion.
