PORTER Porter Original 3-Way Briefcase [B4 Compatible] HEAT Heat Navy Amazon Limited Rare Original Briefcase I have been using the Heat 3-way for work for many years, and I purchased this one previously for use in my private time. As an exclusive item, it was a limited edition that could only be purchased on Amazon for a limited time. The color is dark navy, although it's difficult to tell in the photos. Unlike the regular Heat items, the material is Strongtex nylon, and the interior is rescue orange, like the Tanker series. It has only been used once, for a short time, and is almost new. The following is the description: On the front exterior, there is a key ring x 1 and a zipper pocket x 1. When you open the zipper pocket, there is a pocket that is convenient for storing smartphones, etc. It is made of elastic mesh material that securely holds the contents. Inside, there are two pockets that can hold a Kindle HD, one pocket that can hold a laptop up to 15 inches, and three pen holders. The main compartment zipper is a U-shaped double zipper that opens from either the left or right side when used in the backpack style. Height 31cm x Width 43cm x Depth 11cm x Handle height 11cm I think it's unlikely that an item in this condition will appear on the market. I will sell it to anyone who is looking for it. I am not able to offer a discount on this item. Color: Blue
