This bracelet is made from nickel free pewterwire that I've braided and then sewn on to soft vegetable tanned leather from reindeer. The button is made of antlers from reindeer which they shed in late fall here in Sweden. Convo me for requests on other colors of leather or wire. I will happily work with your favorite color :) ★ Because all Reindeers are Individuals, the color of the antler button may vary. ★ Size: The Bracelet is 0.9 cm (5/16 ") wide. Custom Size - This will be made upon your order to fit perfectly on your wrist. State the measure of your wrist in "Message to seller" The leather is vegetable tanned, free of heavy metals. The reindeer hide is from reindeer that has been roaming freely in the Swedish mountains. Pewter thread is nickel free.
