Custom Flask

The 500ml Sona Vacuum Flask gives businesses and organizations a straightforward drinkware option for carrying custom artwork and a removable filter.

Its 500ml capacity is about 16.9 fluid ounces, offering a useful midsize option for everyday branded merchandise. The flask measures 23 x 6.3 cm, or approximately 9.06 x 2.48 inches, making its dimensions easy to review when planning gift sets, event merchandise, employee packs, or other bulk programs.

One defining feature of the Sona model is its included removable filter. Because the filter can be removed, the flask gives recipients the flexibility to use the main flask with or without that component, rather than making the filter a permanent part of the setup.

For buyers comparing several promotional beverage products, RAFFLESTAG also offers a broader range of custom drinkware options for different campaigns and recipient groups.

Four Solid Colors for Coordinated Orders

The Sona Vacuum Flask is shown with four solid color choices:

• Silver
• Black
• Sky Blue
• Dark Green

This selection gives buyers both neutral and more distinctive color directions. Silver and Black work well when an organization wants restrained merchandise, while Sky Blue and Dark Green add visual variety.

The product configuration also displays a separate quantity field for each color. That is useful when planning an order that uses more than one available color rather than assigning the entire quantity to a single option.

For example, a company could use different flask colors for separate departments, event groups, campaign themes, or gift recipients while keeping the same Sona flask format. You can enter the final color allocation directly through the available quantity fields.

A Useful Size for Branded Merchandise Programs

At 500ml, the Sona offers a versatile capacity for organizations choosing branded drinkware. Buyers can evaluate the 23 x 6.3 cm dimensions alongside the way the finished item will be distributed.

For employee merchandise, the flask can become part of an onboarding or internal recognition program. Event organizers can use it as attendee merchandise, while companies can incorporate it into customer or partner gift selections.

Organizations considering a bottle-style alternative can also compare the Sona with RAFFLESTAG's custom water bottle range. Comparing formats before ordering can help buyers decide whether a vacuum flask, water bottle, or another drinkware style fits the intended recipients more naturally.

Upload Your Artwork for Customization

The Sona configuration includes an artwork upload area, allowing buyers to provide the design they want associated with the flask order. An order-notes field is also available for additional instructions related to the customization request.

When preparing artwork, keep the main logo, name, or message easy to recognize. A simple visual hierarchy is especially useful for promotional merchandise because recipients should understand the branding without having to study a complicated design.

If you include text, prioritize the most important wording rather than trying to fit multiple messages into one design. A company logo, event name, department identity, campaign graphic, or concise promotional message can provide a clear direction for the finished customization.

The available product information doesn't show the exact customization method, so the product content should describe the flask as supporting custom artwork rather than assigning a specific printing or marking process.

Planning Quantities Across the Available Colors

Color allocation can be an important part of a bulk drinkware order. Because separate quantity inputs are displayed for Silver, Black, Sky Blue, and Dark Green, buyers can plan the order around recipients instead of choosing colors only after deciding the total quantity.

A business preparing merchandise for several teams might assign a different color to each group. An event organizer could use two or more colors to distinguish attendee categories. A company preparing gifts could simply mix the available shades to create more variety while maintaining a consistent product style.

The key consideration is deciding the required quantity for each selected color before completing the configuration. This makes the order structure clearer and helps keep the chosen color distribution aligned with the intended use.

Where the Removable Filter Adds Flexibility

The included removable filter distinguishes the Sona from a basic flask configuration. Because the component is removable, recipients aren't limited to keeping it installed every time they use the flask.

This can be particularly useful for gift programs where recipients may have different preferences. Instead of selecting separate flask models for people who may or may not want the filter component, the Sona provides one format with the filter already included and removable.

For buyers who prioritize a different drinking format over a filter-equipped flask, RAFFLESTAG's custom tumbler collection offers another drinkware category to compare.

Choosing the Sona for Corporate and Event Orders

The Sona is especially relevant when a buyer's selection criteria include a 500ml capacity, removable filter, customizable artwork, and a choice of solid colors.

Corporate buyers may consider it for employee merchandise, internal programs, business gifts, or branded packs. Schools, organizations, clubs, and event planners can also use a customizable flask when they want recipients to receive a functional item featuring organization-specific artwork.

The available color selection can also help connect the flask to an existing visual theme. Buyers can choose a single color for a uniform presentation or enter quantities across several available colors for a mixed-color order.

What to Review Before Configuring Your Order

A simple way to evaluate the Sona Vacuum Flask is to focus on the confirmed choices that affect the order.

First, make sure the 500ml capacity and 23 x 6.3 cm dimensions suit the intended merchandise program. Next, decide whether the included removable filter is useful for the recipients you have in mind.

Then choose from Silver, Black, Sky Blue, and Dark Green, and decide how to split the total quantity across the selected colors. Finally, prepare the artwork you want to upload and use the order-notes field for relevant customization instructions.

This keeps the purchasing decision centered on the features and options actually available for the Sona model.
