12 Pack Stainless Steel Skinny Tumblers 20oz - Bulk Insulated Set

In this review the 12 Pack Stainless Steel Skinny Tumblers is presented as a practical bulk option for small events, crafters, and families who need uniform insulated drinkware. The bottom line: this set is worth considering if you want a blank, durable 20oz tumbler that stays cold for hours and is ready for DIY personalization; the packaging of 12 individually boxed tumblers plus lids and stainless straws makes it simple to distribute or gift. The review focuses on build quality, insulation performance, and suitability for customization.

Key Features

• Quantity: Twelve individually boxed tumblers provide consistent branding or gifts for events without extra packaging work.
• Material: Made from 304 stainless steel so the cups resist rust and are sturdy enough for repeated use.
• Insulation: Double wall vacuum insulation keeps beverages hot for up to 6 hours and cold for up to 12 hours, which helps maintain drink temperature during long outings.
• Size and fit: The straight 20oz body is about 8.1 in tall and 2.9 in diameter, designed to fit most car cup holders for everyday convenience.
• Complete set: Each kit includes a dishwasher-safe-seeming lid alternative, a stainless straight straw and a straw brush so the set is ready to use and clean manually.
• DIY friendly: The blank black finish is suitable for vinyl decals, painting, or other personalization for gifts or events.

Who It's For

The set is ideal for party planners, wedding or bridal shower hosts, craft sellers, and small businesses that need a uniform, blank tumbler for personalization or resale. It also suits households that prefer buying insulated drinkware in bulk to replace disposable cups or to keep matching tumblers on hand.

It is less ideal for someone who wants a tapered or specialty-shaped tumbler, or for users who require dishwasher cleaning as the manufacturer recommends hand washing and notes the tumblers are not intended for dishwasher use.
