20 oz Skinny Tumblers Bulk 12 Pack - White Vacuum Insulated

Our review of these 20 oz skinny tumblers finds them ideal for someone who wants a durable, no-fuss insulated cup for daily use. The biggest reason to buy is consistent temperature retention in a slim, cupholder-friendly shape: the double wall vacuum insulation keeps drinks cold up to 9 hours or hot up to 4 hours while the powder-coated 18/8 stainless steel resists rust and wear. For anyone who travels, commutes, or wants a matching set for family or events, this bulk pack delivers reliable performance without complicated extras.

Key Features

• Double wall vacuum insulation: Keeps cold drinks chilled for up to 9 hours and hot drinks warm for up to 4 hours so beverages stay at a predictable temperature on the go.
• No-sweat exterior: The insulated, double wall design prevents condensation, keeping hands and car cupholders dry during use.
• Durable stainless construction: Made from 403 18/8 stainless steel with a powder coat finish, the tumbler resists peeling and rust for long-term use.
• Slim, portable shape: The skinny profile fits most cupholders and is easy to carry, store, and pack for travel or outdoor activities.
• Included lid and straw: Each tumbler arrives with a plastic slide lid and reusable straw for spill reduction and easy sipping.
• Bulk set convenience: Twelve identical tumblers make this a practical choice for parties, offices, or gift-giving occasions.

Who It's For

These tumblers suit people who want a reliable, slim insulated cup that fits car cupholders and works for both hot and cold drinks. The pack is great for families, offices, event hosts, or anyone who prefers a coordinated set of travel cups with simple lids and reusable straws.

Buyers who need a true leakproof travel mug with locking seals or insulated bottles with carry handles should look elsewhere; this product emphasizes a slim, splash-resistant design over heavy-duty leakproof performance or extra accessories.
