GOLDEN KEY 87oz Thermo for Hot Food – Large Vacuum-Insulated Lunch Jar with 3 Stackable Inserts

Overview

The GOLDEN KEY 87oz Thermo for Hot Food is a spacious, stainless insulated jar designed to simplify meal transport for work, travel, and everyday life. It combines a generous outer capacity with a practical internal layout, making it possible to carry hot or cold meals with confidence. While the body can hold up to 87 ounces, the usable portion is about 51 ounces, which can fit multiple portions or shareable meals depending on your plan.

What makes it stand out

• Three stackable inserts: two 18.90-ounce portions and one 12.85-ounce portion, housed in a double-layer system with a 304 stainless steel interior and a food-grade PP exterior.
• Tailless vacuum technology to help maintain temperature; hot soups may stay warm for several hours, while cold items can remain fresh for longer periods.
• Materials chosen to be BPA-free and PVC-free, with a wide-mouth opening for easy filling and thorough cleaning.
• Air-valve lids on each insert to ease opening while preserving the seal and insulation performance.
• Versatile use cases—from daily office dining to travel, picnics, and outdoor meals—with the option to pair with an insulation bag for extended time between meals.

Practical use and tips

This thermo set is designed for people who want to portion meals ahead of time and keep them at a desirable temperature during the day. The three inserts help you organize meals by type or course, while the wide mouth makes filling and cleaning straightforward. For best insulation results, preheat or precool the storage jar for a couple of minutes before adding food.

• For best results with hot foods, preheat the container with hot water for 2–3 minutes before filling.
• Pair with an insulation bag to extend heat retention or cooling time during commutes and outdoor activities.

Care and longevity

The interior is designed for long-term reliability and is BPA-free. Hand washing is recommended to extend the life of the seal and finishes, though the wide-mouth design makes cleaning easier. If you encounter any quality concerns after delivery, the product team offers support and a hassle-free return or exchange policy.
