50 Pack Sublimation Tumblers Bulk 20 oz - Ready for Customization

In this review of the 50 Pack Sublimation Tumblers Bulk, the bottom line is simple: this bundle is aimed at small businesses, crafters, and event planners who need a high-volume, ready-to-print option for personalized drinkware. The standout reason to buy is the consistent high quality sublimation layer on each straight-sided 20 oz stainless steel tumbler, which transfers designs clearly and produces vibrant color results while also offering reliable thermal performance for everyday use.

Key Features

• High quality sublimation coating: A dedicated sublimation layer allows clear, bright transfers so prints reproduce fine detail and saturated color reliably.
• Completely straight cup shape: The straight 20 oz profile makes wraps and full-coverage designs much easier to align and press compared with tapered cups.
• Double-layer vacuum insulation: Built from 18/8 stainless steel with vacuum insulation to keep drinks hot for about 9 hours and cold for about 12 hours for real-world use.
• Complete bulk kit packaging: Each order includes 50 tumblers plus lids, straws, straw brushes, silicone bases, shrink wrap, separate boxes, paper and high resistant tape to speed production and shipping.
• Individually boxed units: Every tumbler ships in its own box for easier gifting, storage, and resale without additional repackaging.

Who It's For

This pack is ideal for crafters, small print shops, and event coordinators who need a consistent, easy-to-sublimate blank that can be produced in volume. The included supplies such as shrink wrap, tape and paper reduce the need to source extras and help streamline a production workflow.

Those who should look elsewhere include buyers who want a single custom tumbler or a variety of shapes and sizes; this product is a straight 20 oz blank in bulk and not intended for one-off premium, handcrafted tumblers or those needing specialty finishes beyond sublimation.
