MAXWIN launches K‑SHBAG01 multi‑function car seat box in Japan

MAXWIN introduced the K‑SHBAG01, a three‑in‑one car interior accessory that serves as a storage box, waist‑support cushion, and handheld bag. The unit holds up to 30 L of items and is built from polyester with a PE‑plus‑aluminum insulated layer that keeps food and drinks cool or warm. It measures about 34 × 37 × 24 cm in box mode and 34 × 24 × 8 cm as a cushion, weighs roughly 1.2 kg, and includes a stopper that slides into the seat gap for tool‑free installation. The high‑density cushion material supports the driver’s lower back during long trips. The product is marketed for everyday grocery runs, camping, barbecues and other outdoor activities and is sold through major Japanese e‑commerce platforms such as Amazon Japan, Rakuten and Yahoo! Shopping.
