Liberty Oil is a 100% synthetic oil that comes in a 4-fluid-oz bottle with a stainless steel needle tip dispenser. Because it is premium quality 100% synthetic oil it easily outperforms all other oils on the market. This oil contains two friction modifiers that bond and protect the metal and act like tiny ball bearings to reduce friction and wear. The perfect oil for all hobby uses. The bottles are new using LDPE, which is a very soft plastic that is easy to squeeze. You will also receive a 1.5 inch 18-gauge stainless steel needle tip that is of pharmaceutical grade with patented Luer lock cap to insure that you have no leaks from your bottle and cap. Do not use any other oil to lubricate your Watches again!!! I have a 100% positive feedback with my oil so you can buy with confidence. I am an authorized reseller of this product ask the other guys and you will get no response or the runaround. If you are not 100% happy with your purchase I will refund your money with no questions asked.
