Glass bowls are necessary for a bong to work! They are a removable slide that attaches to a bong serving the purpose to hold your cannabis in place, ready for you to light up.
Glass bong bowls can come in many shapes, styles, and sizes but it's important to note that they come with either a male or female joint. When looking for a new bowl, you need to choose the one that is the opposite gender of your bong.
Ex: If you have a bong with a 18mm male joint, buy an 18mm female jointed bong bowl.
Luckily at Mary Janes HQ we carry a variety of sizes, and joints so you can find whatever tickles your fancy, and ensure it fits your bong! Go ahead and have a look!
