Easy to carry: needle tip bottles can be used to dispense liquid, with a rubber stopper, not easy to leak, and easy to carry. Product material: needle tip bottle is made of polyethylene, non-toxic and odorless, with good chemical stability and can withstand most of the acid-base erosion.
These little thin tip bottles are great to use for many things. I use them for crafting. I put glue in them for better precision when applying the glue to projects. Good product. I recommend them.
