O My O-Rings! Sometimes a D-Ring just won't do. These 1" O Rings are not your typical lightweight O Rings, each of these weigh in at 0.4oz with the interior being a true 1" opening. The actual size of the O Ring is 1 3/8". Available in Antique Brass, Brushed Gold, Rose Gold, and Gunmetal and Nickel finishes that will help add bling to any bag!
