100 Silver/Chrome Shiney MINI Bottle Caps! We get all of our bottle caps straight from the manufacturer, without all the writing, insignia and rubber liners that you will find in bottle caps from other suppliers. Mini Bottle Caps: * We are proud to launch our newest product, the Mini Bottle Cap! * The Mini Bottle Cap measures 1/2" across the top, 5/8" across the bottom and is only 1/8" thick. * It is perfect for all of those projects that require something smaller than our normal Bottle Cap US Steel in a manufacturing facility located right here in the USA.
