This is a magnetic frame specifically for Brother's professional embroidery machine PR series. It's a user-friendly type, similar to those used in commercial machines like Tajima. The frame comes with a magnetic shape. ※ This product is not subject to discounts. You'll be freed from the struggle of stretching fabric without wrinkles! It's very convenient, so please give it a try. You'll be amazed at how easy it is to frame your work. Your productivity will be completely different. It's cheaper than the price of a genuine cap frame, and you can get a cap frame and magnetic frame. It's a great deal.
