Our company is proud to introduce the WL-8528, a luxury Rectangle Black Box designed for executives and professionals who want a container that matches their high-end style. Unlike plastic boxes that look cheap, the WL-8528 features a matte black plastic exterior with genuine leather accents on the lid and a metal logo plate—elevating it from a functional item to a stylish accessory.
Measuring 238*193*50 mm, the WL-8528 Rectangle Black Box fits perfectly into briefcases and luxury backpacks. The interior has a recessed design to prevent food from sliding during transportation. The lid closes with a snap cap that closes quietly (no loud clicking noises during sessions) and creates a leak-proof seal.
Safety and luxury go hand in hand: the plastic is BPA-free, microwave-safe (up to 120°C), and easy to clean with a soft cloth. It also comes in a premium gift box, making it a great corporate gift for clients or employees
“We wanted to create a lunch box that doesn’t look like a box,” said the design lead. “The WL-8528 Rectangle Black Box is for professionals who refuse to compromise on style—even with their container. It’s luxury you can take to the office.”
The WL-8528 rectangular black lunch box is now available in our online store. This exquisite box allows you to experience luxury anytime, anywhere.
