Even expensive oils are usually in plastic jug / - filled vials whose spout leaves to be desired most left. The well-known plastic-cutting closure with cap is not optimal. With the purchase of High Tech chain fluid 105 Refill Innot. Refill Refill 1ltr. have here a pot with dosable spout. The jug (the Oilers) closes tightly (it can also fall without leaking), the metal grommet is drawn out to about 10 cm and screwed it firmly and the spout tip is again adjustable for themselves (like the formerly so common was). You can lubricate the famous one drop or more very sensitively and accurately. The transparent bottle body in a handy size shows the oil level. So the oils enjoy! I immediately ordered my two oilers to even to have a different type of oil accurately dosed at hand. Recommended to buy!
