Collection: Flasks by Type uses state-of-the-art equipment to customize and personalize our hip flasks.  There are many different methods, some of which are confidential, but the 4 main machines we use to create your custom flasks are a digital printer for creating color all the way around the hip flask, an ultra-violet printer for creating two-sided full color graphics and text, a mechanical engraver for etching into the stainless steel and a laser engraving machine for burning into the front or backs of the hip flasks.  These 4 machines are very expensive and take highly skilled workers to operate but we do it and are still able to keep our flasks affordable! You can also design your own flask from scatch here.
