Fine-tooth cutting set for Moser Rex Mini - Precision-ground stainless steel cutting set "Made in Germany" - Grooved profile for perfect glide and optimal cooling - Extra fine tooth spacing for detail work. Important: To ensure a long lifespan, it is essential to regularly oil the cutting head as described in the user manual. Without a sufficient oil film, metal will rub against metal, causing the cutting head to wear out quickly. Please note: Dirt and sand in your dog's coat can also dull cutting heads during grooming. Therefore, it is advisable to wash and thoroughly dry your dog's coat before grooming.
