The Old Wives' Tale That Really Works: "Drop a copper penny into the vase with your flowers to help keep them fresh for longer."When it comes to keeping cut flowers looking fresh, the aim of all home remedies are to keep icky, slimy, sticky things from developing in the water. Where does the copper come in? It helps keep flowers alive because it naturally cleans your vase water. We're making this home remedy even better by introducing our 100% copper charms, thicker and heavier than an old penny, and better looking, too. It is reusable, eco-friendly, and comes in a micro suede cloth bag for safe-keeping between uses. Rather than digging around for old pennies, get yourself our cute copper charm or give it as a gift to your flower loving friends. Note: You'll actually be digging for really old pennies since any penny made AFTER 1982 is made with mostly zinc and contains less than 3% copper. We made sure that our charms are made of PURE copper. There are many products that are copper colored, but aren't actually made of copper.Southern Living, Apartment Therapy, and Readers' Digest all agree, copper is a smart way to keep flowers alive. And don't just take our word for it, read our reviews. We recommend using one charm for small and medium vases and two charms for larger vases.
