The Wahl Oil Tube 118ml keeps the shaving and cutting blades on trimmers and hair clippers in mint condition. The contact between blades will stay smooth and oiled, ensuring the blades stay sharp for longer. Remove all hairs and apply 1 or 2 drops of oil after use. Then switch on the device, allowing the oil to spread out. 118 millimeters will suffice for years to come. On top of that, it's also very suitable for (home) barbers.
