This is ski and snowboard wax that I used about 10 years ago. Wax is a paraffin substance, the same as a candle, and is a stable substance, so there should be no chemical changes. 1. Base wax: 6 unused bars remaining. This is for base coating, but if you're just playing around, this is sufficient. It will prevent the tail from catching on the snow surface, allowing for a smooth glide. Apply this base coat, then apply the next wax depending on the snow temperature and quality. 2. TOKO 135 wax: Unused. I bought several sets and used them, but some are still left. The red wax in 1 is for powder snow, the silver wax in 3 is for rain or melting, sticky snow, and the yellow wax in 5 is for fresh, wet, and heavy snow. 3. Wax scraper (plastic, yellow): Used to remove excess wax from the sliding surface after applying wax. 4. Edge sharpener: A simple, portable sharpener for polishing the metal edges of skis and boards when they are rusty or damaged. It's a metal file. The edge width can be adjusted with a screwdriver. It was very convenient and useful at ski resorts. The above is a set price. Price negotiations are not accepted. No returns or exchanges, please.
