12 Pack Sublimation Tumblers Flat Edge Blanks Skinny Straight 20 oz

In this review the 12 Pack Sublimation Tumblers Flat Edge Blanks Skinny Straight 20 oz are evaluated for crafters and small-business decorators looking for an economical, ready-to-print set. The kit's biggest selling point is that it is designed specifically for full-wrap sublimation work: each tumbler is completely straight with a flat bottom and a white polymer coating that accepts transfers cleanly. Included accessories aim to save time in production, and the stainless double-wall construction means the finished cups are durable for everyday use.

Key Features

• 12-Pack kit: Includes 12 tumblers plus 12 straws, 12 shrink wrap sleeves, 12 rubber bottoms and 12 individually boxed units to simplify storage and shipping.
• Flat edge base: The flat bottom provides a cleaner sublimation edge and reduces ghosting for a neater full-wrap print.
• Completely straight body: The non-tapered, skinny straight shape makes it easy to apply a continuous design without gaps or distortion.
• Made for customization: The white polymer coating is set up for sublimation, decals, glitter or paint, letting creators personalize each tumbler easily.
• Stainless double wall: Fabricated from 304 stainless steel with double-wall insulation for better durability and temperature retention after finishing.

Who It's For

This pack is well suited to hobbyists, craft fair vendors and small custom-gift businesses that need multiple blank tumblers for heat transfer and vinyl work. The included shrink sleeves and individual boxes make it practical for producing and shipping batches of personalized cups.

People who want a single artisan tumbler or expect a tapered design should look elsewhere, because these are straight skinny blanks optimized for full-wrap printing rather than for a niche ergonomic shape or single high-end drinkware piece.

Pros & Cons

Pros

• Consistent full-wrap results thanks to the flat bottom and straight sides.
• Complete accessory set in each pack reduces the need to source extras.
• Durable 304 stainless steel and double-wall construction maintain drink temperature and robustness.
• White polymer coating produces vibrant color quality with sublimation prints.

Cons

• Some customers report mixed experiences with the lid closure, so lids may require attention to ensure a tight fit.
• Because these are blanks optimized for sublimation, they are not pre-decorated and require a sublimation printer and heat process to finish.
