At the Bomb Headshop we focus on quality control and only carrying top products so while some of our competitors, shops may carry items that we don't have, you can be assured that our products are top notch.
In fact, we take quality control very seriously.
We've delisted plenty of products before, and stopped working with vendors that don't uphold our standard of quality. We think this is so important that it's in our mission statement: Good Business comes from good people working with good people. We won't ever sell you a product that we ourselves would feel uncomfortable using - every product we decide to carry is weighed as important decision with the customer (you!) in mind.
In our experience, working with our preferred American glass companies assures that our glass is always top-notch and holds up even after years of use. There are plenty of American Glass pieces to fit every budget.
