5-Pack 1 OZ Bottles with Stainless Steel Needle Tip for Gun Oils - Precision Lubrication for Firearms, Tools & Machinery (Ideal for Gun Maintenance, DIY Projects & Industrial Use)

This is what I've been looking for! Good LDPE bottles w/ lids that screw down snugly and have a needle applicator.These bottles use the standard Luer-lock needle attachment that's commonly used in the medical field.Bottles are perhaps thinner than I'd anticipated, but not detrimental at all. Just don't squeeze hard w/ thin liquids, or you'll get more than you bargained for.I'm very familiar w/ LDPE plastic, and it is a long-lasting, fairly durable material. Being as soft as the LDPE is in these bottles, I'd suggest not cranking down the lid super hard - just snug is sufficient. Over-tightening can 'stretch' the threads on the bottleneck enough to let thin liquids seep by. Just be advised.I'm also happy w/ the needle length. Many other bottle sellers have short, stubby needles. Those are just fine for many jobs, but sometimes you need to get lube into a far-back and tight spot that those shorty needles can't reach.One thing I'm not sure about is whether they will leak/seep if tipped over or upside-down. I've read reviews that say yes and some that say no. I don't intend to carry these in a range bag or toolbox; they're just going to live on my benchtop.One observation I can report is that the needle caps seem to seal well. Users of Eezox will tell you that if left out w/o a lid, the 'cleaner' fraction of Eezox will slowly evaporate, leaving a slightly thicker mix of lubricant and metal conditioner/preserver. I personally use Eezox often and extensively, and have not noticed any evaporation through these bottles when the needle cap is on.I'll be getting more of these soon.
