25pack 20oz flat edge sublimation tumblers - Ready for Custom Prints

Our review of these 25pack 20oz flat edge sublimation tumblers finds them ideal for small businesses, crafters and event planners who need a bulk set that sublimates cleanly and holds temperature. The single biggest reason to buy is the flat edge and polymer coating, which together make full-wrap heat transfer designs much easier and more consistent than on rounded bottoms; this turns a batch sublimation run into a predictable process and reduces wasted cups. The set also includes lids, straws, silicone bases and individual window boxes so finished tumblers are ready to gift or ship.

Key Features

• Flat Edge: The flat bottom gives a full, even surface for dye sublimation and reduces edge distortion so patterns line up reliably.
• Complete 25pc Kit: The package includes 25 tumblers, 25 metal straws with brushes, 25 sliding lids, 25 silicone bases and 25 window white boxes for immediate finishing and gifting.
• Polymer Coating: Pre-coated cups are formulated for heat press or convection oven transfer so designs adhere and colors come out vibrant.
• Insulated Construction: Double-wall stainless steel vacuum insulation helps keep drinks cold for extended periods and offers a durable everyday cup.
• Sublimation Settings Included: Recommended heat press time and temperature and oven guidance are provided to help achieve consistent results when using a heat press or oven.

Who It's For

These tumblers suit craft sellers, makers and party planners who need volume and consistent sublimation results; the flats bottoms and coating simplify full-wrap designs and the included boxes make them gift-ready. The metal straws and silicone bases add perceived value for customers receiving a finished product.

People who should look elsewhere include buyers who want single custom tumblers or premium, thick reusable straw options, since some customers reported the straw quality is weaker than the cups themselves. Also, if you need dishwasher-safe guarantees for the printed wrap, test a sample first, as sublimation durability depends on application method.
