This listing is for Colorful and Economical Aluminum Blanks! They will add a fresh look to modern jewelry pieces and are also great for a variety of crafts! They measure 37mm and are .8mm thick, so that is 1 1/2" in diameter and 20 gauge thick. The hole is 3.1mm.
What makes these ECONOMICAL? They are stamped from a sheet of anodized (colored) aluminum so the ends are not colored and they may have rough edges. There are some occasional marks and scratches as well, but they are a great PRICE! Each listing is for 8 or Buy in Bulk and Save!
The holes will accommodate 10 gauge jump rings but we like to use 16 gauge 4mm ID jump rings. Find them here: https://www.etsy.com/listing/85021236/100-silver-aluminum-jump-rings-handmade
They do not contain nickel or lead.
