How well does it keep drinks cold or hot?

The Grenada uses double-wall vacuum insulation to limit heat transfer and condensation. In independent-style testing scenarios, it preserves ice-cold drinks for up to 24 hours and maintains hot beverages for up to 10 hours, all while the exterior stays comfortable to hold.

• Double-wall vacuum technology for extended temperature retention
• No exterior condensation with cold drinks
• Maintains hot liquids without making the outer shell too hot to handle

Constructed from 18/8 food-grade stainless steel, the Grenada is corrosion-resistant and built for frequent use. The materials are BPA-free and lead-free, and the rhinestones are professionally secured to withstand typical handling.

How should I care for the rhinestone finish and the tumbler overall?

To preserve the sparkling finish and internal performance, hand wash with mild soap and warm water and avoid abrasive cleaners or scrubbing pads. Allow the tumbler to air dry completely before storing to protect the rhinestones and maintain the seal on the lid.
