Keep your hands and lips occupied in parties with this GRAV Martini Glass Bubbler. As part of the GRAV Sip Series, this bubbler makes it easy to party with your friends and socialize at the same time. Inside the glass piece is a Martini shaped chamber that ends with a custom-fitted, enforced perc. You can dance around with it and the smoking system will stay in place. No worries about spills here. With the long straw and Dewar seal connection, the water stays inside the bubbler. Have a grand time, and unleash the social butterfly in you!
