Halloween Silver Spider on Web Charm Eek!! A spider!!....Oh, sorry! This is a silver charm that features a spider sitting on it's web. It measures 5/8 inches from the top of the loop to the bottom and 1/2 inches across and is flat on the back side which makes it easy to glue in place. Great for Halloween ATCs and other spooking projects. You will receive one charm for every quantity that you order.
