20 Pack Sublimation Tumblers 20 oz Skinny Straight Flat Bottom - Bulk

In this review of the 20 Pack Sublimation Tumblers 20 oz set, the bottom line is simple: crafters who make custom drinkware will appreciate a complete, beginner-friendly kit that consistently produces vibrant sublimation results. The set ships with 20 white 20 oz skinny tumblers, individual gift boxes, splash-proof lids, straws and brushes, rubber bottoms and shrink wrap film, so most of what is needed for heat transfer projects arrives in one package. The upgraded angled flat bottom and straight skinny shape reduce white space and alignment issues, making it especially useful for small businesses, craft fair vendors and hobbyists testing larger batch runs.

Key Features

• Complete kit: Each tumbler arrives with a splash-proof lid, straw, brush, rubber bottom and shrink wrap film so crafters can start sublimating immediately without hunting for accessories.
• Upgraded angled bottom: The redesigned right angle bottom helps the sublimation transfer sit flush and avoids white gaps, producing more consistent edge-to-edge prints.
• Absolutely straight 20 oz skinny shape: The straight, narrow profile simplifies tape alignment and reduces the chance of misprints, which is helpful for beginners.
• Individual gift boxes: Taller individual boxes hold the cup and accessories together for gifting or retail presentation without additional packaging work.
• High quality sublimation coating: The white coated surface takes dye sublimation well, enabling bright color reproduction with a heat press or sublimation oven.
• Multi-use practical design: The tumblers are suitable for daily commuting, office use and outdoor events once finished, so they make usable custom gifts.

Who It's For

The set is aimed at crafters, small business owners and teachers running craft sessions who need a batch of uniform, sublimation-ready tumblers for personalization or resale. Because 20 identical cups are included with packaging, the kit is convenient for making coordinated gifts, party favors or retail inventory without buying parts separately.

It is less suitable for someone who only needs a single tumbler or a handful, since the pack is bulk and intended for multiple projects. Also, customers who require specialized lid designs or double-wall insulation should look elsewhere, as these are single-wall coated blanks made for heat transfer.
