This item is specially made to be filled with flowers. Whether it is a large bunch or a subtle hanging plant, this item will do your plants justice. Floran's eco glass is produced from recycled glass, the glass that everyone takes to the glass container. Because there is always a bit of pollution in recycled glass you can see some irregularities, which makes each item unique. Also, this glass is not entirely clear and seems to have a blue-green glow. Isn't it great how this process works? No waste and beautiful, usable products!
