Beautiful handmade furnace glass created by designer David Christensen. David' s artistry is represented here in a single long round tube shape. The bead is unique and definitely is a work of art. The bead measures 53x12mm with a 3mm hole size. It is perfect to use with the beadable pens. We recommend pairing it with one of our beadable pens, but the choice is always yours. You may have another use in mind. Either way, this bead is sure to create a positive reaction.
