Stvyar 20oz Sublimation Tumblers Blanks — 8-Pack White, Double-Wall Stainless Steel with Two Lids

Stvyar 20oz sublimation sport tumblers are double-wall stainless steel blanks with a flat edge, ready-coated for full-wrap heat-transfer designs and supplied with two lid styles for versatile drinking.

These 20oz tumblers come as an 8-pack of pre-coated, straight-sided stainless steel cups created especially for dye sublimation and heat-press transfers. Each cup includes two lid options — a flex straw lid and a sliding lid — plus metal straws, shrink wrap sleeves, and rubber bottoms so you can produce finished, gift-ready tumblers right away. The flat bottom and consistent diameter make full-image sublimation simpler and reduce ghosting at the base.

How do these tumblers simplify sublimation printing?

The Stvyar blanks are pre-treated with a polymer coating designed to accept dye sublimation inks, giving crisp, full-color transfers without additional priming. Their straight, identical top-to-bottom profile and flat edge ensure more even heat and pressure during wrapping or oven processing, which results in cleaner image alignment.

• Pre-coated polymer surface for dye sublimation compatibility
• Flat bottom and straight walls for easier full-wrap transfers
• Shrink wrap sleeves included to stabilize prints during curing

What lids and accessories are included, and why do they matter?

Each tumbler arrives with two lid styles so you can offer options: a flexible straw lid for sipping and a sliding lid for spill resistance. The pack also contains metal straws with cleaning brushes, rubber bottoms to prevent slipping, and individual boxes that make them easy to store, ship, or gift after customization.

• Flex straw lid for hands-free sipping and on-the-go hydration
• Sliding lid to reduce splashes and help seal beverages
• Metal straws, brushes, and rubber base pads included for convenience

Will these tumblers keep drinks hot or cold?

Built with a double-wall, vacuum-insulated stainless steel construction, the cups reduce heat transfer and help maintain beverage temperature longer than single-wall options. While results vary by use and environment, the insulation is designed to extend enjoyment of both hot and cold drinks during daily activities.

• Double-wall stainless steel for thermal insulation
• 20oz capacity fits standard cup holders and travel needs
• Durable construction suited for repeated everyday use

How consistent are these blanks for producing multiple units?

Stvyar supplies this set as an 8-pack of uniform tumblers, so sizes and coating quality are consistent across the batch, which helps maintain a predictable production workflow. The identical dimensions and finish reduce variability when you print multiple copies of the same design.

• Eight tumblers with matching diameters for batch consistency
• Individually boxed pieces for organized storage and transport
• Shrink sleeves included to produce repeatable, professional results

Who is this for: Small businesses, crafters, and hobbyists who create custom drinkware will appreciate the ready-to-print coating, uniform shape, and included accessories. If you produce event giveaways, personalized gifts, or a shop collection of printed tumblers, this 8-pack offers the materials and options to print, finish, and present your work with minimal additional supplies.
