This is a glass pen from Hase Glass Studio. It's a beautiful color, like a blue-green. I was drawn to the shifting colors and bought it. Purchased several years ago. Used only for a test write. Stored in a box in a dark place. I'm selling it to declutter. Available for immediate purchase. The pen itself, the box, and the pen rest will be carefully packaged and shipped. Please understand that this is a used item and purchase after confirming the condition in the images. #HASE Glass Studio #Borosilicate #Glass Pen #Green #Blue #Aqua #Green
