This is a special edition Mantis 26, a collaboration between ARC'TERYX and BEAMS. Purchased online from BEAMS. I have another black Mantis, so I've only used this one a few times for carrying luggage on car trips. The exterior appears to be in good condition, but there is some minor staining inside. The stains are light and should come off easily with a product like Utamaro. I haven't washed it yet, so the water-repellent treatment should still be effective. This model is now discontinued and features a valuable gold tag in a BEAMS-exclusive white color. I've taken care of it to the best of my ability, but please refrain from purchasing if you are overly concerned about minor details. I am not considering lowering the price.
