Maruhachi Kasei's luminous brand 'OUROBOROS' completed its 7th crowdfunding campaign for a large-size glow-in-the-dark carabiner. The project achieved 1,668% of its goal, raising approximately 1.67 million yen from 559 supporters.

Maruhachi Kasei Co., Ltd., a plastic injection molding manufacturer based in Nagoya, announced the successful completion of its 7th Makuake crowdfunding project for the 'Glow-in-the-Dark D/S Carabiner Large Size' on May 18, 2026.

Built on the concept of 'Wearing Light,' these Japanese-made carabiners glow vividly in the dark, attracting significant attention from outdoor enthusiasts, disaster prevention-conscious users, and pop-culture fans (oshi-katsu). The campaign raised a total of 1,668,500 yen with 559 supporters, reaching 1,668% of its initial target.

The large-size model was developed in response to user feedback requesting bigger carabiners. The increased dimensions allow attachment to pipes and other large structures where previous models could not fit. Key use cases include marking tent pegs and flashlights at night, or as visibility aids in emergency kits.

Founded in 1974, Maruhachi Kasei has over 50 years of experience in plastic manufacturing. The carabiners are made from proprietary glow-in-the-dark polycarbonate, offering both high visibility and a unique aesthetic. Every step of production is handled in-house to ensure the high precision expected from Japanese craftsmanship.

Moving forward, the company plans to launch general sales on Rakuten and Amazon. They are also eyeing international markets, specifically the United States and Taiwan, while developing new colors and specialized disaster prevention products. CEO Masanori Kaneda stated, 'We will continue to showcase our challenges in material development and manufacturing to the world.'
