Maruai Co., Ltd., a paper products manufacturer based in Yamanashi Prefecture, will release a new line of letter sets called "MINERA" on March 9, 2026. The collection features four designs inspired by minerals and gemstones, offering unique textures and patterns.
Translucent Sealing Wax-Style Stickers Add Special Touch
The MINERA series was designed to meet the growing interest in handwritten letters as a thoughtful means of communication in an increasingly digital world. With consumers seeking not just meaningful words but also aesthetically pleasing designs that add a special touch to their correspondence, Maruai developed this new collection to expand their letter product lineup.
The collection includes four varieties inspired by different minerals: Blue Lace Agate, Pink Amethyst, Jade, and Marble. Each design captures the distinctive colors and patterns reminiscent of the actual gemstones, giving each letter set its own unique character.
The letter sets come in two sizes: a standard size suitable for mailing (standard postage), and a mini size perfect for attaching to gifts. Each set includes translucent stickers designed to resemble sealing wax, which can be used for sealing envelopes or as decorative accents. These three-dimensional, elegant stickers add a premium feel to the letters.
