These are handmade brass or copper metal buttons, available in 2-hole style. This series is only available in 1" These metal buttons have been created with an appreciation to the tiny pollinators that surround us! I am selling each pattern on their own, but certainly package them as the "Pollinator Packs" or sell individually as focal buttons. These buttons have been slightly cupped to add to their functionality. All metal I use is lead free and of jeweler quality. I use no harsh commercial aging agents in my process. If not aging naturally, I use the power of vinegar and/or heat! When etching, I use an electrical current in order to etch my plates. No acid is used in this process. The etching bath I use is good for a lifetime, unlike acid that is good for one use and then is toxic. I am as green as possible in my metalworking process.
