This is a 13mm replacement blade for a Thrive clipper. As you can see, the blade width is wide, so it's not suitable for pets. It has been cleaned and sharpened. I tested it on a wig with Thrive and Speedik clippers. I applied grease & oil when assembling it, but it's not overly greasy, so add more if needed. Discounts available if you buy multiple items. It will be shipped in a simple box as it doesn't have its original packaging. Please judge the condition from the photos. Barber Beauty Trimmer Speedik
