This double mushroom chain collar pin is so stylish. It makes any shirt collar look classy and cool. Crafted from durable solid (not plated) raw brass with a push pin back. I added a patina to enhance the vintage feel and highlight the texture. The Double mushrooms measure 11mm tall by 13mm wide and the short chain is 5 inches, the long chain 7inches. Each double mushroom has a solid brass push pin back, see pictures. Be sure to check out all my other mushroom as well! ***Please Note!*** Some shirt collars have a hard plastic tab inside them for support. This plastic will need to be pierced with a thick sharp needle or thumbtack before inserting your collar pin piece. Your collar pin is not designed to pierce hard objects, it is a piece of jewelry to be handled gently with care. ✦ C A R E - I N S T R U C T I O N S ✦ Each creation is lovingly hand crafted with meticulous attention to detail, aesthetic, and durability. Please remember to remove your jewelry before bathing/showering, swimming, doing rigorous physical activities, or working with harsh soaps, lotions or any chemicals. Sterling silver and brass are metals that will tarnish and react to their environment. Proper storage can help prevent this. Keeping your jewelry in an airtight container is best, as the air and humidity can speed up tarnish. Wearing your pieces as much as possible will help keep them tarnish free as your skins natural oils help protect the metals from tarnishing. Polishing occasionally by rubbing or with a sterling silver polish will help remove any dullness or tarnish.
