The Saeshin Strong 105L Carbon Blue Brush Handpiece is a professional replaceable handpiece designed for technicians who need stable performance, comfortable handling, and compatibility with standard nail drill bits. Your product title and SKU align with the 35K version for Strong 210, while current seller pages confirm the same product naming and SKU SA003.

Performance Note
