This green bead pen allows you to showcase your favorite large-hole beads in a place where they can get the attention they deserve. Try it with Fire Designs hand-blown furnace glass beads. We are also partial to using fun and colorful lampwork glass beads with the bead pen. The metal rod that connects the two parts of this metal pen has a width of 2.5mm, so plan your beads accordingly. Screw the longer threads into the bead pen cap and screw the shorter threads into the bead pen itself. Try creating your own combination of beads for a personalized look. Note: The ink in this pen is blue.
