Who knew a stopper could be so impressive? The Stonylab Glass Hex Head Hollow Stopper is a game-changer for any lab looking for a closed bottom solution for their 24/40 outer joint. The hex head adds a touch of pizzazz to an otherwise mundane piece of equipment and the glass material ensures durability. With five packs included, you'll have plenty to keep your lab running smoothly. Five stars from me!
