To clean your flask, rinse it with warm, soapy water right after you finish your drink. Then, turn it upside down to let it dry completely before reattaching the lid. The flasks are not dishwasher safe; we recommend hand washing them for the best care.

Aside from the aesthetics, the Firelight Flasks have a slightly wider mouth to accommodate ice cubes than the Parksides, and the Firelight tumblers are slightly larger featuring double-wall vacuum insulation (whereas the Parkside 750's tumblers are double-wall insulated). The Parksides and Firelight 375 & 750s both share the respective volumes and the tumblers attach magnetically. Both flasks are double-wall vacuum insulated and equally temperature efficient - the only difference in insulation is in the tumblers.

We do not recommend putting carbonated beverages in your flasks. Aside from a potentially messy filling process, Carbonation creates pressure and gas buildup within the flask that can cause a spray upon opening. Excess pressure may also lock the cap’s threading permanently, rendering the flask unusable. Any damage related to carbonation inside a High Camp Flask will void the products' warranty to any related damages.

These customizations are made-to-order and applied via precision laser engraving resulting in an extremely high-end finish that makes for an excellent gift or personal memento.

We can customize products in any quantity from one-off gifts to large bulk orders. Explore our custom products options here, or learn more about our bulk custom program here.

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.

Custom orders take approximately 3 weekdays to engrave. Once engraving is complete, delivery time will depend on the shipping method you selected:

Estimated Transit Times:

• Standard Shipping: 2-7 weekdays
• Expedited Shipping: 2-3 weekdays
• Overnight Shipping: 1-2 weekdays
