Spleen 3D Silk Eye Mask (Evening Whisper) Spleen, a self-care brand that proposes "10 minutes before sleep" to disconnect from smartphones and reconnect with oneself, will begin general sales of its first product, the "3D Silk Eye Mask," which achieved 151% of its goal on the crowdfunding service Makuake, on its own online store starting July 1, 2026. Also from the same day, Spleen will open a pop-up store for a limited time until September 30, 2026, at "CHOOSEBASE SHIBUYA," a media-type OMO store located on the 1st floor of the Seibu Shibuya Parking Building. This will be an opportunity to directly experience the feel of the highest quality silk and the unique 3D structure, not just online. ■ Pre-sale on Makuake Achieved 151% of Goal Makuake Project Spleen focuses on the decline in sleep quality due to modern information overload and smartphone dependency, proposing a new approach to regulate sleep through "experience" rather than just "function." In the pre-sale held on Makuake from March to May 2026, the product received many supportive comments such as "My nights have become something to look forward to" and "I was looking for an eye mask that doesn't press on my eyes," ultimately achieving 151% of the target amount. ■ General Sale Starts July 1 & Limited-Time Pop-Up at CHOOSEBASE SHIBUYA Following the positive response on Makuake, general sales will begin on the Spleen official website (online store) from July 1, 2026. Furthermore, a limited-time pop-up store will be held from July 1 to September 30 at "CHOOSEBASE SHIBUYA," a media-type OMO store with the concept of "Encountering meaning, buying intention." At the store, you can directly try the feel and fit of the actual product, along with an exhibition that expresses the world of Spleen's proposed "10 minutes before sleep." The product will also be available for sale simultaneously on CHOOSEBASE's online store. 【CHOOSEBASE SHIBUYA Pop-Up Store Details】 • Period: July 1, 2026 (Wed) - September 30, 2026 (Wed)
