I'm selling this because I no longer use it. About two-thirds of the product remains. Roche-Thomas' Premium Slide Cream (1 ounce) is manufactured with a special blend that does not use wax or grease. By applying a very small amount to the slide inner tube stockings and using a water spray, you can maximize the smoothness of the slide, and it also has high durability, achieving extremely comfortable slide work. Roche-Thomas' Premium lubricant manufacturing line uses a special filtration process to remove impurities and residues, and all products are blended and bottled in a US factory. A unique process produces a clean-coat, fast-acting lubricant that does not produce dust or lint. Image 3 is a size comparison with a trombone mouthpiece. Please refrain from purchasing if you are overly concerned about details.
