6pcs Dropper Steel Needle Bottles Tip 7 Sizes Plastic Drip E-juice Liquid Filling Squeezable Childproof Mix Color(3ml+Mix Color Pack of 6pcs)

*****1 year Update:I use these for my e-liquids for vaping, but they can be used for oil, paint, glue, alcohol and dozens of other things. I hadn't realized these could be used for actual line painting... that's really cool! I'm thinking maybe food coloring would work well too.Just remember the gauge of the needle tip is narrow, so thick liquids take a hard squeeze to apply. Vaping with pure Vegetable Glycerin means slow loading if you use tank mods (not much trouble for drip), so I pulled out one of the needles and use that larger hole for filling my tanks at home. The other 5 bottles still have the needle tubes attached. When the bottle is empty I just swap lids. With the needle removed I can fill the tank in one or two seconds. I just used pliars and pulled it like a tooth.No LEAK problems... not even once, and these go everywhere with me... even to Asia several times so far.I need to WARN parents though, even though the title says "childproof" there are absolutely NO precautions. They are NOT childproof.Original Review:Quick review here to make it clear that there are indeed 6 bottles and 6 colored lids... pic made that unclear. Good quality and low price. Only possible critical point would be that the stoppers are hard to get on the first time. These will be useful for my e-liquid home lab since the tops are easier to remove instead of re-using the pop-off spouts on old e-juice bottles.

I recently started growing plants in my aquarium and I needed an easy way to add tiny amounts of fertilizer and other nutrients. These are easy to use and dispense very precise small droplets! All the tips are the same gauge but the different color caps help avoid confusion. The little silicone caps fit nicely on the tips and there is no dripping or mess.

Bought both 15mL and 30mL bottles. The bottles held both alcohol and oil without any problems. The seals on the lids are very good. Squeezing viscus fluids from the bottles did not show any leakage from the pressure.

They're sturdy bottles with well-fitting needle-tops. I don't know what gauge the needles are, but high VG eliquids are a bit too thick for them. It's doable, but keep in mind that it's going to be slow. Great overall bottles.

As described, look forward to another purchase.

Great product - high quality, excellent value. The plastic stopper for the dropper needle works very well. I bought them to rescue some silicone oil from a defective bottle. Arrived much sooner than estimated.

Good product...ships faster than expected.

Great quality, preformed just as expected they should without fail.
