Uxcell Precision Needle Tip Plastic Applicator Bottle 50ml with White Cap 10 Count The needle tip bottles are great for DIY and repair: ink liquid glue oil fluid paints and other low viscosity liquids. Also suitable for lubricating hinges cleaning switches lubricating bicycle chain etc. These bottles are made of soft flexible PE plastic. Cap fits tightly easy to fill and hole in tip is just right. They dispense accurately without dumping too much onto your target. Very easy to use. The size of the opening is quite small which means you can produce very small dots. To clean you should fill the empty bottle with warm water and squeeze it out through the needle. Just be sure to clear the metal tube after you are finished so as not to clog it. Also as an advice if using for dispensing purpose do not fill the container more than half. This makes it easier to dispense accurately.
