Our upcycled mini glass bottle fridge magnet is up for grabs. Add this cutest, greenest magnet to your fridge. Our Eco-friendly fridge magnets are kiln-formed in a furnace at 800 degrees Celsius. All Tiger and Twig upcycled products are made from glass bottles that were destined to be in the landfill. Each piece & color might vary from each other depending on the waste material available. Let's make it cool to care with Tiger and Twig.
