Thank you for viewing. Based on the dimensions, I believe this is an SKB/3i series model, specifically the "3I-2217-8B". It's a large case. I purchased it used, but it didn't fit my needs, so I'm selling it. ■ Technical Specifications (※ The following values are from the manufacturer) ・Internal Dimensions Width: 55.9 cm (22 inches) Depth: 43.2 cm (17 inches) Height: 20.3 cm (8 inches) ※ Lid: 5.1 cm (2 inches) / Base: 15.2 cm (6 inches) ・External Dimensions Width: 61.8 cm (24.3 inches) Depth: 49.5 cm (19.5 inches) Height: 22.5 cm (8.9 inches) ・Temperature Resistance Maximum: 82.2°C / Minimum: -56.1°C ・Weight: Approximately 5 kg ● Before listing, I washed the exterior with detergent and dried it. ● There is urethane foam glued to the inside, which was molded to fit equipment. (Photo 20) ● I'm including a free SKB and Pelican urethane foam (worth 10,000 yen) with pre-cut grid lines, although it's not specifically for this case. (Photos 16, 17, 18) ● There are some scratches on the outside of the case. Please check the photos. This does not affect its usability. ● As it's a case, I will ship it in simple packaging, wrapped only in air padding. ● A new case with urethane foam costs around ¥50,000. The following is a copy-paste: Specifications By using reinforced polypropylene material, the product's durability against gasket corrosion and impact is improved, creating a product with excellent waterproof and dustproof properties. Furthermore, its product quality clears strict military security standards. ■ SKB/3i Series "3I-2217-8B" Specifications List ・Waterproof/Dustproof Specifications ・Meets standard MIL specifications ・Uses "Ultra high-strength polypropylene copolymer resin" as the raw material, making it resistant to UV and heat and less prone to deformation ・Features a grip handle that fits comfortably in the hand ・Uses a patented "trigger release latch system" for the locking hardware ・By using the optional "3i-TSA-3", you can easily replace it with a TSA lock.
