The Windsor Silver and Rope Bracelet was both designed and skilfully handcrafted completely in Great Britain. Combining British craft manufacturing with a discerning modern-minimalist style, this ANCHOR & CREW bracelet features: 3mm diameter performance Marine Grade polyester and nylon rope (GB) Secure solid .925 sterling silver button-shaped hook clasp (GB) This bracelet is one size fits all, with the rope able to extend or tighten to suit your wrist size. To take the bracelet on or off your wrist, simply slide the one adjustable knot around the rope to make the loop size smaller or larger, and once set, keep the loop size consistent and continue wearing by easily unhooking the button-shaped hook from the loop.
