12 Pack Sublimation Tumbler Blank 20 oz Straight Skinny - Craft Kit

In this review of the 12 Pack Sublimation Tumbler Blank 20 oz Straight Skinny, the bottom line is simple: this set is best for crafters, small business owners, and gift makers who want reliable, machine-ready cups that take color well. The reviewer found the kit valuable because each stainless steel tumbler arrives individually boxed with shrink wrap, non-slip bases and plenty of accessories, making it an immediate workstation-ready choice for batch sublimation projects and personalized gifts.

Key Features

• Complete sublimation kit: Each tumbler is gift boxed and includes 12 non-slip silicone bases, 12 shrink wrap sheets, 1 heat tape and 50 stickers so projects can start right away.
• Dual-opening lid: The exclusive lid offers two opening methods, GulpPro for larger sips and SipEase for smaller, child-friendly sips, giving flexible drinking options.
• High-quality coating: The sublimation polymer coating is applied evenly to provide a smooth surface for vibrant, full-color transfers.
• Food-grade stainless steel: Constructed from 18/8 stainless steel, the straight skinny tumbler is durable and suitable for everyday drink use.
• Vacuum insulated design: The double-wall vacuum layer and screw-in lid help keep drinks hot for hours and cold even longer, useful for on-the-go use.
• Sublimation-ready instructions: The package notes recommended temperature and press times and suggests shrink wrap for best results to achieve consistent transfers.

Who It's For

This set suits hobbyists and small makers who produce custom tumblers for holidays, birthdays and events, and anyone who wants to start sublimation projects without sourcing multiple accessories. The included shrink wrap, bases and stickers reduce prep time and make batch printing more efficient.

It is less ideal for someone needing heavy-duty commercial lids or for buyers who expect the lid assembly to withstand rough, long-term use without occasional replacement. Those who require an insulated bottle with advanced spillproof features might prefer a different insulated bottle design.

Pros & Cons

Pros

• Strong value: multiple tumblers plus accessories let crafters make a dozen pieces without extra purchases.
• Good sublimation results: the even polymer coating yields saturated, accurate color transfers.
• Versatile lids: the two opening methods accommodate both adult and child drinking preferences.
• Insulation: vacuum layer and screw-in lid provide useful temperature retention for hot or cold drinks.

Cons

• Durability of lids is mixed: some users report lids break or wear faster than the steel body, so spare lids may be needed.
• Heat resistance feedback varies: follow the recommended temperature range and press times to avoid inconsistent results.
