Stainless Steel 36 Pack 20 oz Insulated Tumblers - Bulk Set

In this review the Sieral 36 pack 20 oz insulated tumblers are judged as a practical bulk solution for events, offices, or gift giveaways; the single biggest reason to buy is the combination of quantity and reliable double wall construction that keeps drinks at temperature while offering a broad range of colors for easy identification. For anyone needing numerous durable travel cups for a party, workplace, or laser-engraved giveaways, this set delivers strong value, though a few customers note lid fit and size preferences may vary.

Key Features

• 36 pieces in mixed colors: A dozen different colors mean groups can assign or personalize cups easily and the supply is large enough for parties or employee gifting.
• 20 oz capacity: The roughly 600 ml capacity suits most hot and cold beverages from coffee to juice without feeling oversized for typical use.
• 304 stainless steel with double wall: The construction provides thermal insulation to help maintain drink temperature and prevents quick external condensation.
• Powder coated finish: The coating adds a gripable surface and a colorful look that customers have found attractive and suitable for laser engraving.
• Practical lids with straw hole: ABS lids include a detachable rubber ring for better sealing and a push lid and straw opening for spill reduction and convenience.
• Wide occasion use: The set is positioned for weddings, graduations, office use, and holiday parties making it versatile for many events.

Who It's For

This 36 pack best fits event planners, small businesses, or families who want a ready supply of matching-but-varied tumblers for gatherings or giveaways, and anyone who plans to customize cups by laser engraving for gifts or branding. The large quantity and color variety make it a practical choice when many recipients need a durable, insulated cup at once.

Those who prefer a single premium-brand feel or who need a larger capacity should look elsewhere, and buyers sensitive to lid fit should test a sample first if possible, since a minority of users reported lid sealing issues and a few noted lids could feel warped.

Pros & Cons

Pros

• Good value for bulk purchase with solid build quality in 304 stainless steel.

Cons

• Some customers report occasional lid seal or fit problems, so lids may not be uniformly perfect across all 36 pieces.

Specifications

Our Verdict

The Sieral 36 pack 20 oz tumblers are a strong value for anyone needing many insulated cups at once, offering durable 304 stainless construction, a colorful powder coat that engraves well, and useful double wall insulation. They are recommended for events, office supplies, and gift use, but buyers should be aware of occasional lid fit variation and choose this set when quantity and customization are priorities over single-unit premium branding.

Frequently Asked Questions

Can these tumblers be engraved?
Yes, the powder coated stainless surface is reported to work well with laser engraving for names or logos.

Are the lids leakproof for travel?
The lids include a rubber seal and push lid to reduce spills, but some users report inconsistent fit so they are spill-resistant rather than guaranteed leakproof.
