Custom Flask

The RAFFLESTAG 1200ml Stainless Steel Insulated Vacuum Flask gives businesses and organizations a larger-capacity option for customized drinkware. At 1200ml, or 1.2 liters, the flask provides approximately 40.6 US fluid ounces of capacity, making it a useful choice when a standard smaller bottle is not the right fit for the intended audience.

Its stainless steel construction and insulated vacuum flask format give the product a clean, recognizable drinkware profile. The product images show a tall cylindrical body with a looped detail at the top, creating a distinctive appearance without adding unnecessary visual complexity.

For companies sourcing coordinated promotional merchandise, this flask can sit alongside other options in RAFFLESTAG’s custom drinkware collection. Comparing the flask with bottles, tumblers and mugs can help buyers select a format that suits the way recipients are expected to use their branded item.

Four Solid Colors for Different Brand Directions

The flask is offered in four solid colors: Silver, Black, Sky Blue and Dark Green. Rather than limiting an order to one visual direction, the ordering interface provides a separate quantity field beneath each color.

That setup is useful when planning an order for different departments, teams, attendee groups or campaign themes. A company could, for example, allocate different available colors to different internal groups while maintaining the same uploaded artwork.

Silver provides a neutral metallic-looking base in the product selector, while Black offers a darker presentation. Sky Blue introduces a lighter color choice, and Dark Green provides a deeper natural-toned option. When choosing a flask color, buyers should consider how their artwork will visually contrast with the selected background.

Simple logos, company names and bold graphic elements are generally easier to assess visually when there is a clear distinction between the artwork and flask color. If your branding contains fine lettering or several small elements, reviewing its legibility at the intended display size is especially useful before submitting the artwork.

Upload Your Branding During the Order

Customization is built directly into the displayed ordering process. Buyers can upload their artwork file and provide additional information through the order notes field.

The artwork upload allows a maximum file size of 10 MB. This gives you a clear limit to work within when preparing a company logo, organization emblem, event graphic or other branded design.

The order notes field can be used to communicate relevant design instructions that accompany the uploaded file. For example, notes can identify the intended logo version, explain which part of a supplied design should be used or distinguish between several elements contained in one artwork file.

Keeping the artwork and instructions organized helps make a customized order easier to understand. Before uploading, check that names, dates, spelling, phone numbers, web addresses and other text inside the design are correct. Those details are particularly important for event merchandise and company-branded products because errors inside supplied artwork can become part of the final visual.

Choosing the Right Color Mix

Because all four colors have their own quantity boxes, buyers can plan the color allocation while building the order rather than treating color as an afterthought.

A single-color order can create a consistent look across an employee or event program. A mixed-color order can be useful when the same artwork needs to serve several groups while still allowing some visual variation.

For example, an organization could select Black or Silver for a more neutral company presentation and use Sky Blue or Dark Green when those choices better match a specific event or campaign palette. The important point is to evaluate each selected flask color together with the actual artwork rather than choosing both independently.

The same principle applies when comparing different types of custom drinkware. A desk-focused program may benefit from exploring RAFFLESTAG’s custom glass mug options, while traditional branded mug formats can be compared through the custom mug selection.

Suitable for Business, Organization and Event Branding

A custom 1200ml flask can fit a variety of promotional and organizational programs. Businesses can incorporate it into employee merchandise, customer gifts, company events, conferences or branded campaigns. Schools, clubs, associations and event organizers can also use customized drinkware when they want an item carrying their own artwork.

The larger 1200ml capacity can be particularly relevant when the buyer intentionally wants a substantial drinkware item rather than a compact cup or small bottle. That distinction can help narrow down product selection before quantities and artwork are finalized.

For employee programs, keeping one artwork design across several flask colors can create consistency while still giving recipients a choice of appearance. For an event, selecting one flask color may instead produce a more uniform presentation across the full order.

Building a Coordinated Gift Presentation

The flask can also be considered as one component of a wider branded gift program. If a campaign includes multiple items, buyers can coordinate artwork, colors and presentation across the different products rather than designing each piece separately.

Packaging is not part of the visible flask configuration shown here, so businesses planning a separate gift presentation can compare RAFFLESTAG’s custom gift box options independently. This is useful when the drinkware will eventually be combined with other merchandise as part of an employee, customer or event gift set.

Preparing a Cleaner Artwork Submission

Before submitting the order, review the uploaded design at a practical viewing size. Logos with very thin lines, tightly spaced text or highly detailed graphic elements may be harder to read when reduced. A cleaner version of the same branding can often create a clearer visual result on promotional drinkware.

It is also useful to avoid uploading several unexplained logo variations in the same file. When multiple versions are necessary, use the order notes to identify which design should be used.

Keep the file within the displayed 10 MB upload limit and verify that the final artwork contains the exact wording intended for the flask. These simple preparation steps make the customization information more straightforward and help keep the product, color selection and supplied branding aligned within one order.
