Chillums are small glass hand pipes, also referred to as bats, one-hitters, or onies. Measuring just a few inches, they are just about the smallest smoking pipe you can add to your arsenal. Perfect for those on-the-go, beginners, and discrete users as they are pocket-sized. Grab one for hiking or your next trip to the beach and you can enjoy yourself without any hassle. These affordable and simple pipes do not have a carb, so there is less airflow control which results in stronger hits.
