12 Pack 20 oz Sublimation Tumblers Dual Opening Blank Bottles - Bulk

In this review of the 12 Pack 20 oz Sublimation Tumblers, the reviewer finds a practical bulk kit for crafters and small businesses who want consistent, printable drinkware. The main reason to buy is the complete sublimation-ready package: a dozen straight-sided 20 oz stainless steel tumblers with lids, shrink wrap, rubber bases and heat tape that make batch personalization straightforward and reliable for events or resale.

Key Features

• Complete kit: Includes 12 blank 20 oz tumblers, 12 shrink wraps, 12 rubber bases, 50 waterproof stickers and 1 heat transfer tape, which saves time sourcing parts for a batch project.
• Dual opening lid: The lid offers two drinking options so users can sip directly or use a straw, providing versatility for hot or cold beverages on the go.
• Straight shape and flat bottom: The straight-sided design gives a larger, even printing area that helps achieve cleaner, more detailed sublimation results compared to tapered cups.
• Triple-insulated stainless steel: Durable construction and insulation help maintain drink temperature for hours while resisting corrosion in everyday use.
• Sublimation-ready coating: The surface is formulated to accept vivid, fade-resistant prints, making it suitable for intricate heat transfer artwork.
• Easy to clean: A wide mouth and smooth interior simplify washing and maintenance between custom jobs.

Who It's For

This kit is aimed at hobbyists, crafters and small business owners who produce customized tumblers in modest batches and need consistent, sublimation-ready blanks plus basic finishing supplies. The included shrink wrap and heat tape make it useful for users who plan to press multiple items in one session.

It is less suitable for someone who only needs a single custom cup or expects heavy-duty commercial lids; a buyer who prioritizes an ultra-durable lid mechanism or individual premium packaging might prefer single-item premium options instead.

Pros & Cons

Cons

• Lid durability is a reported weak point; some users experience breakage under regular use.
