If you are purchasing a Swix T60 Wax Roller, make your life even easier, get a spare wax tray (or 2 or 3). Dedicate one tray to each of your most often used waxes. In the US, most people get a tray for 6, 7, 8 and Base Prep. That way you never have to clean out a wax tray to put a different wax in, you always have what you need at the ready. The spare wax tray includes the lid.
