Prym Anorak Metal Snap Buttons, 15mm, copper color, in a pack of 10 units, reference 390312 BB, are snap buttons suitable for jackets and anoraks, eliminating the need for a traditional buttonhole. Prym is a German brand founded in 1530 in Aachen, the oldest family-owned industrial company in Germany, now based in Stolberg and recognized worldwide for needles, pins, buttons and sewing accessories. This snap fastening system is faster to open and close than a traditional button, and is common in outerwear and technical clothing. The 15mm gauge is larger than the 12mm of the same line, making it a preferred option for more robust jackets that require a larger button.
