How to customize a High Camp Flask.

This video will walk you through the three different ways you can customize your High Camp Flask.


What does engraving look like?

We use a laser etching process that removes the outer coating of finish from the product to reveal the stainless steel material beneath. Unlike screen printing, laser engraving won’t rub off or chip over time. The preview/mockup generated in our customizer is only an approximation of how the engraving will look.

Example of custom engraving
When will I get my engraved flask?

We engrave and ship orders placed on our website using our customization platform in 3 business days or less. We only ship using regonized carriers.

You will receive your personalized flask in as little as 7-10 days.

Perfect travel companion1

I often travel for work. Being able to enjoy a cocktail and unwind after a long day of travel and work is priceless! I already had the 750 for overlanding with my wife, so I knew the 375 would be perfect for a couple of night solo on the road!

Luis Maldonado

I finally used it for work. I love it thank you

Coper was not very copper colored

The black and silver flasks were beautiful! The 2 copper ones were specked with copper color and seemed lighter than in your images, making the engraving not very pronounced. I would not order copper again and was disappointed with those. Again, the onyx and gunmetal were terrific.

Hey David - Thanks for bringing this issue to our attention. That looks like a color defect and its covered by our lifetime warranty against manufacturing defects. We will be communicating with you directly via email or phone shortly.

High quality, great service

We ordered a quantity of 36 customized Flask 375s. We had our company logo engraved. Lauren was excellent to work with. She was quick to respond with much appreciated follow-up. I asked for pricing on a few different options and received a proof quickly once selection was made. The turnaround time on this order was important for an upcoming event and they arrived well before we needed them. These are high-quality customer appreciation items for us and they look great!

odd size

Good quality but the medium size doesn’t hold that much. My fault for not paying more attention to product info but i thought it would hold another 20 percent or so. Well designed but not as useful as I’d hoped
