This 4" Inch Boston Bruins Iron-On Embroidery Patch is a bit larger than the standard sizes you normally find. It is made using a 100% thread saturation count, meaning the quality is as good as it gets, just compare our pics to the others you find out there. It also uses top quality embroidery thread in Gold, Black and White. The Iron-On adhesive sheet on the back lets you too easily iron on or heat press.
