This is a leather mat for the Stanley Lunch Box 9.4L. Without a mat, the lunch box can be noisy when in use, but placing a thick leather mat reduces the rattling and improves the appearance. This item was originally made for personal use, but a new one has been created. Leather used: Cowhide, stone wash finish, blue white, approximately 1.9mm thick Leather color: Blue white Photo 1: Usage example (lunch box and lid are not included) Photo 2: Front Photo 3: Back Photo 4: Thickness This leather has a rare blue white color. It's soft to the touch, and I think the color is especially cute. It looks great with the green lunch box, and it's also very cute when used with a white lunch box. If you use a Stanley lunch box and are concerned about the rattling, please give this a try. This is a handmade item. Please purchase only if you understand that it is a handmade item.
