Cupohus Nasal Spray Bottle, 3 Pcs 30ML/1oz Cobalt Blue Glass Refillable Fine Mist Sprayers Atomizers, Travel Sized, Empty Nasal Sprayer with Funnels and Labels

These bottles are excellent, glass is thick and the spray tip is longer then unusual. Spray pattern is a super fine mist! Couldn't be happier with purchase

Works perfectly, love the cobalt blue :)

TL;DR * Good sprayers! * Max fill is ~37ml, NOT 30ml per my measurements! * ~30ml advertised capacity is to about the first curve of the bottle as you go up. * Dispenses ~0.14ml per spray in my measurements. * Didn't break in testing, unlike many competing sprayers I evaluated. * Consider trimming the straws carefully to get an extra ml or so per bottle fill. Product Comparison: I've tested many different spray bottles, and so far, these are the best. The generally available 10ml brown glass bottles usually suffer from dangerous malfunctions of the sprayer that shoot a tiny plastic ring up the nose and have inconsistent spraying amounts. They often fail before a single full use of contents of the bottle is completed. Same with plastic bottles that use the same type of spray head, reusing plastic isn't the greatest. I cannot discern if these bottles use a single piece of formed plastic for the tip, or if the little plastic restrictor is installed from the inside and flush against a small lip. Either way, it's a better design than most other sprayers with a top installed press fit ring. I did not boil these glass bottles for sanitization, as my experience with cobalt glass containers like these, but not necessarily these, is that they tend to degrade and crack under the temperature changes. I also passed on baking sterilization for the same reason, although it tends to be gentler if you bring the bottles up to temp and down from temp slowly. Instead, I used an iodophor product that is common in the beverage industry for cleaning equipment, which I use on the plastic tops for all these anyway, and to my surprise, the plastic didn't pick up much iodine staining, which isn't the usual. That's another nice point. Rinsed with boiled and cooled water. Performance: The nasal spray pattern was very consistent. It seemed forceful at first, shooting quite far in a fine mist. These don't seem to sputter as much as most, shoot streams, or irregular sprays. That's a good thing in my assessment. Moreover, the actual experience was very pleasant, and did not feel remotely forceful due to the fine mist. The straw sat well in the bottle and was trimmed to a reasonable length to curl into the outside edge. The center of the bottom of the bottle is a little raised, so the last bit of liquid ends up around the side. I did feel like this could be improved on by precisely trimming the straw to wedge just in the side. Ensure you cut the straw at an angle and go a little bit at a time if you try this. If you cut it flat, it can roughly seal against the bottom edge and make sprays inconsistent. Still far better than most on the straw. Measurements and Method: I filled the bottle to the brim with water, and carefully attached the top, displacing as little water as possible. This is absolute max fill, and when I measured the remaining water, it came out to approximately 37ml, not 30ml. I measured 30ml into the bottle and the level is approximately one mm up from where the bottle starts curving towards the top. This measurement discrepancy seems normal with all of sprayers I evaluated. Keep this in mind. Using the max fill of ~37ml, I tested how many sprays I could get out of the bottle and ended up around ~270 sprays per bottle on average. That works out to ~0.137ml per spray. A couple of ml remained at the bottom after the sprayer got what it could, but that's normal.

Item was as advertised. Unfortunately we got the wrong size. Totally our fault.

The sprayer is consistent and the glass bottles are good quality. The arrived quickly.

These are really big for a nose situation

Nozzles broke. Sprayed the 1st couple times. Would not consistently spray.

I received them in good condition; the color is exactly what you see in the picture. They work well as a sprayer for the nose. I received them in a timely manner and am happy with them! I have to use the sprayer every 2-4 hours upon waking, they are working well, no leakage in my purse.

Muy proctico y de excelente calidad

Great nasal spray bottles. I’ve ordered twice now as they are perfect for nasal sprays during the flu season.

The item was delivered little earlier than expected , the package was in good condition, no issues there. Kudos to the “overseas seller” the Amazon parter .Plus the spray bottle is just perfect especially with my long fingers

Not ideal for traveling. Leaks easily when not stored vertically

Description says "3 pcs thick glass made 1oz/30ml nasal bottles with non-porous, tasteless, and odorless qualities". It's thin, brittle plastic.
