20 oz Tumbler Bulk 12 Pack Stainless Steel Tumblers - Vacuum Insulated

In this review the Metalya 20 oz tumbler 12 pack is evaluated for small businesses, crafters, and event planners who need a consistent, engravable cup in bulk. The single biggest reason to buy is the combination of food-grade 18/8 stainless steel construction and a colored powder coat that is ideal for laser engraving and custom decoration, making it a practical base for personalized gifts or branded giveaways. The set balances everyday functionality with creative potential, while remaining a budget-friendly option for groups and projects.

Key Features

• Premium material: Made from food-grade 18/8 stainless steel for durability, corrosion resistance and a clean drinking surface.
• Double wall vacuum insulation: Keeps drinks at a stable temperature for extended periods so both hot and cold beverages perform better than single-wall cups.
• Colored powder coat: The blue-purple plated finish is designed to reveal a contrasting metal layer after laser engraving for clear, attractive personalization.
• Slip-in lid with straw: Transparent AS sliding lids and included straws provide spill reduction and easy sipping for daily use and travel.
• 20 oz capacity: The tapered, sleek shape fits most car cup holders and holds a generous serving of coffee, iced drinks, or water.
• Bulk convenience: Twelve identical tumblers provide consistency for events, corporate use or craft projects where uniform appearance matters.

Who It's For

This 12 pack is best for small businesses, craft sellers, event coordinators and teachers who need a consistent canvas for custom engraving or vinyl work and prefer a durable stainless steel cup that resists rust. It also suits families buying in bulk for daily use, holiday gift sets, or meal prep where matching drinkware is handy.

Those who want the absolute best long-term temperature performance or a fully leakproof travel mug should look elsewhere, since some users reported mixed results on how long beverages stay cold and the sliding lid is not a locking, leakproof design.
