This one's for those who want the best of both worlds. Made of 100% borosilicate glass, this 8" Red Eye Glass® Concentrate Beaker has such a timeless shape that you all know and love and includes a 19mm male 90 degree quartz banger. Feelin' like changing things up and smoking some flower instead? Just switch out the banger for a 19mm bowl and you're good to go. Dual purpose, same awesome hits.
