This is not a sale of clippers. This is a sale of compatible ceramic blades. You can simply attach this ceramic blade to your genuine ER9900 or ER9920. While it won't cut as short as our compatible fade blades, it's possible to cut to about 0.3mm. The blade extension may vary depending on the clipper model. Replacing and cleaning the blades that have lost their sharpness can somewhat restore their cutting ability, making them useful in emergencies. Consider keeping them as a backup. Please note that the sound will be slightly louder than with genuine blades. I am selling these because I have switched from ceramic blades to stainless steel blades, which offer improved cutting performance. Available in white and black, but I will generally send the black blade. ⚫︎ To minimize shipping costs, some parts may be processed. There are no issues with usage. Shipping will be via standard mail. In this case, the blade portion will be protected with bubble wrap due to thickness, but the base will be placed directly inside as it will not break.
