10Pcs 3mL Plastic Dropper Bottles with Metal Needle Tip | Leak Proof Squeeze Applicator, Travel Portable Mini Dispenser for Oil, Glue, Paint, DIY Crafts - Translucent & Blue Cap

Love these little needle tip bottles. I use them for fountain pen inks. The needle tips make it easy to refill cartridges or converters without constantly dipping into my main bottle of ink so I can reduce the risk of contamination. I have bought from several different vendors over the years and I don’t think I’ve ever had any leak when screwed together properly. They can eventually develop issues with the needle part pushing in or pulling out of the lid or with the end of the needle poking through the little rubber cover part, though…at that point they just need to be replaced unless you have spare lids and covers.

I use one of these for applying MG Chemicals 835 100ML Liquid Rosin Flux to electronics connections for soldering. It works very well for that purpose. The bottle does tip over easily, but that's OK since the attached stoppers keep the flux from spilling out. I like them. I have 9 more to use if I ever need another one. I'm not a hoarder. Really.. I'm not!

Overall is a nice handy little dispenser for any kind of stickiness that you happen to be running into. The little silicone needle covers keeps everything nice and tidy.

Great little bottle for use as an oiler or dropper. I use it as a precision oiler, it works very well.

Cap seems fine. However they’re not very squeezable. I need to use two hands.

Overall was very great!. I just wish they had more verity for these too another shaped carrier orrrr other bottles made from silicon more flexible and with more needle nosed tops!

They leak

This is the perfect size for my craft projects, so I was excited to try these. I use needle-tipped squeeze bottles to apply acrylic paints to canvas and also to apply underglaze to ceramic work. These bottles are NOT squeeze bottles. They are much too stiff for that, so are not good for my purpose.

Great bottles for precise dye placement. I like the 50ml size as it's not too large to hold for my smaller hands. I mix in larger bottles that have squeeze tops, and squeeze the dye into the smaller bottles. One thing to note: the top opening is quite small and they do not come with a funnel. For me that's fine as the squeeze bottles fit the opening, but for others, you may find that you'll need a funnel that will fit small bottles.
