20 oz Sublimation Tumblers 25 Pack Bulk - Straight Skinny Cups for DIY

In this review of the 25 pack 20 oz sublimation tumblers, the bottom line is simple: this set is for crafters who need consistent, beginner-friendly blanks in bulk. The reviewer found the straight skinny shape and upgraded angled bottom make transfer alignment and heat wrapping far easier, while the included splash-proof lids, straws, brushes and individual gift boxes add real convenience for gifting or resale. For anyone doing heat press or oven sublimation and wanting reliably bright prints without white gaps, these tumblers deliver consistent results.

Key Features

• 25 pack with accessories: Each set includes 25 white tumblers plus a lid, straw, straw brush, rubber bottom and shrink wrap film so projects are ready to start.
• Upgraded bottom design: The angled straight flat bottom reduces white space during sublimation for more complete edge-to-edge prints.
• Slim 20 oz shape: The skinny straight profile simplifies tape placement and makes the cups especially forgiving for beginners using heat transfer presses.
• Individual gift boxes: Taller boxes fit the tumbler and accessories together, making the finished product easy to present as a customized gift.
• Sublimation coating: A high quality coating produces bright, saturated color when used with a heat press machine or sublimation oven.
• Indoor and outdoor use: The cups work well for daily commute drinks, office use, beach and outdoor events when paired with the splash-proof lid.

Who It's For

These tumblers are aimed at small business owners, craft fair vendors and hobbyists who make multiple customized drinkware items and need identical blanks to speed production. The pack size and included accessories eliminate frequent reordering and help assemble gift-ready items quickly.

Less suitable are single-project users who only need one or two tumblers, since the 25 pack is intended for volume. Also, if a user requires insulated stainless steel blanks rather than coated sublimation cups, they should look for a different material option.
