It can be used to oil drop by drop and extremely sparingly. The drip oiler is manufactured for us with an aluminum housing into which the pump is pressed. Thanks to its mechanics, it can also handle oils with a significantly higher viscosity than its cheaper relatives, which is why it is also suitable for Ballistol. If the drip oiler is stored in a cool cellar, it is advisable to warm it up a little before use (holding it briefly in warm hands until it reaches room temperature is sufficient). This reduces the viscosity of the oil, the oil becomes smoother and the drop oiler works better.
