New 'Brown' Color Added to Sold-Out Collaboration School Bag! 'Gloomy Bear' x 'ROCO NAILS' School Bag Re-release and New Color Launch on June 1st

Matsumura Shoten Co., Ltd., a subsidiary of MUSCAT GROUP, which specializes in niche-top brand production, announced the re-release of the 'GLOOMY x ROCO NAILS School Bag (with plush mascot)' following its rapid sell-out. A new 'Brown' color will be added alongside the restocked 'Black' version, available on Rakuten and Amazon starting June 1, 2026. This collaboration combines the popular 'Gloomy Bear' character by Mori Chack with the iconic Heisei-era school bag brand 'ROCO NAILS.' The bag includes a plush mascot of Gloomy dressed in 'JK Gal' fashion, wearing a plumeria flower, which is the symbol of ROCO NAILS.
