50 Pack Sublimation Tumblers 20 oz Skinny Straight - Bulk for Printing

In this review of the 50 Pack Sublimation Tumblers 20 oz Skinny straight set, the bottom line is clear: this kit is built for crafters, small shops, and gift makers who need uniform, print-ready tumblers in bulk. The main reason to buy is the straight, consistent shape combined with a factory polymer coating that takes dye sublimation reliably, making production runs and personalized gifts much easier than working with tapered or uncoated blanks.

Key Features

• Pack size: Fifty identical 20 oz tumblers are included, which simplifies batch production and reduces time spent matching cups.
• Straight design: The tumbler is absolutely straight with the same circumference top to bottom, helping designs transfer without distortion or scaling changes.
• Polymer coating ready for sublimation: A factory-applied coating allows dye sublimation using a heat press or convection oven for bright, durable prints.
• Two sublimation methods: Recommended settings are provided for both heat press (334 F for 50 seconds) and oven (300 F for 6 minutes), giving flexibility to different workflows.
• Insulated build: Double-wall vacuum insulation helps keep drinks hot or cold longer, making the finished tumblers useful beyond decorative use.
• Durable materials: Made from 304 stainless steel with a splash-proof Tritan push-on lid and a silicone base to reduce slipping and noise.

Who It's For

This pack is aimed at hobbyists, etsy-style sellers, event planners, and craft studios that need a consistent blank to produce multiple identical sublimation cups quickly. The quantity and straight profile are especially helpful for anyone doing repeat designs, wedding favors, or custom corporate gifts where color consistency and alignment matter.

Those who should look elsewhere include buyers who need tapered skinny tumblers, single custom pieces, or who do not have access to sublimation equipment or shrink wrap supplies; the product assumes some familiarity with heat press or oven sublimation workflows.
