doublet x Colantotte Debut Collaboration

Unveiled in the 2024/2025 Autumn/Winter Paris Men's Collection


Colan Totte Co., Ltd. (Headquarters: Osaka, Japan. CEO: Katsumi Komatsu), a manufacturer and distributor of the Colantotte brand of magnetic health gear, has cemented its first collaboration with the Japanese fashion brand “doublet” (Headquarters: Tokyo. Designer: Masayuki Ino), which has been officially participating in the Paris Collection since the 2020 Fall/Winter season. The collaboration items, which include necklaces and clothing, were unveiled for the first time as part of the recent Paris Men's Collection, attracting significant attention.



Colantotte's “permanent magnet magnetic therapy devices for home use” are highly reliable managed medical devices certified by a third-party certification body designated by the Ministry of Health, Labour and Welfare. Colantotte's unique Alternating North-South Polarity Orientation (ANSPOTM) allows for the magnetic effect to reach a large area, making it very effective. This manufacturing patent has been acquired not only in Japan, but also in Germany, France, and the United Kingdom. In addition, in 2011, Colantotte obtained the European safety standard CE marking, and Colantotte products are sold in the European (EU) region as Class I medical devices with the CE marking.

Our products are held in high regard for their effectiveness, fit, and design, and we have contracts with approximately 70 top athletes and organizations representing Japan, including Shoma Uno (Toyota Motor Corporation), Yuki Ishikawa, and Mima Ito (Starts). Many top athletes support our products for their effectiveness and design, and they have spread across the globe through domestic and international patent acquisitions.


The “doublet” Brand


doublet is a Japanese men's brand established by Masayuki Ino in 2012.


The brand name "doublet" is derived from Lewis Carroll's "Doublets” word game. Just like the game, in which words are changed one letter at a time, the concept is to replace basic and standard items with sudden ideas, turning familiar items into "everyday wear that’s slightly off." The brand offers a complete lineup including everything from clothing to accessories.


Designer Masayuki Ino


Ino was born in Gunma Prefecture in 1979 and graduated from Tokyo Mode Gakuen in 2002.


After gaining experience as a corporate designer, he worked at a belt factory in Asakusa and then was in charge of planning and production of shoes and accessories at MIHARAYASUHIRO. Afterwards, he established doublet.

He was the first Asian person to win the Grand Prize in The LVMH Prize for Young Fashion Designers, a competition for young designers sponsored by the LVMH Group, in 2018. In the same year, he released a collaborative item with Valentino.

What Sets Colantotte Medically Certified Devices Apart...Is the Colantotte’s unique Alternating North-South Polarity Orientation (ANSPO™) “Experience the Colantotte Difference for Yourself”



The “Alternating North-South Polarity Orientation (ANSPO™)” Makes All the Difference

・Colantotte's magnets are arranged in Colantotte’s unique Alternating North-South Polarity Orientation (ANSPO™), which allows their magnetic forces to affect a large area, influencing the whole surface and not just a single point. This layout allows these magnetic forces to improve blood circulation and alleviate muscle stiffness, assisting the recovery process.


・Our authentic health devices are certified as medical devices and improve circulation around the worn area. Simply wearing them in your daily life can liberate you from the pain of stiffness.

In 2005, Colantotte was launched in America under the overseas brand TRION:Z. Professional golfers Rory McIlroy and Rickie Fowler as well as many other top athletes regularly use this gear to soothe and support their bodies. Additionally, in 2012, one of the Colantotte bracelets was featured prominently as a key story item in the Hollywood movie “The Avengers” as part of a tie-up campaign, demonstrating the recognition of the brand’s quality and design not only in Japan, but by many people all over the world.
