Glass Duckie, You're the One!! Enjoy your dabs with this cute little duck themed oil rig by Crush Glass. Standing between 5" and 6" tall, this little piece is an excellent and adorable addition to your glass collection! This piece has a 14mm Male joint and comes with a glass 14mm female nail. We always recommend buying a quartz 14mm Female nail to go with this piece, as glass is brittle and not the best for use with torches. Grab this cute little Duckie today!
