This is the "Marble Stone - Cloud" from Surisuri Stone. Size: 4.5 x 3.5 cm String Length: 13.5 cm (approx. 30 cm total length) Weight: 39g (including string) A Surisuri Stone is a tool to calm your feelings using the sense of touch. It's known as a worry stone overseas and is well-loved. By stroking it or rubbing the indentation with your thumb, it is said to alleviate and soothe feelings of anxiety and tension. The Marble Stone has a perfect indentation for rubbing with your thumb, and you can expect a relaxing effect. It's also the perfect size and shape to hold tightly in your hand. We are also particular about the materials. The main body is made of Jesmonite, a material that is gentle on the body and the environment. It has a smooth, stone-like texture, and is moist and smooth. The weight is also just like a small stone. The metal fittings are made of brass. The string is made of buffalo leather. Place it by your pillow or on your desk, or attach it to your bag and carry it around, and touch it when you want to change your mood. I decided to make the Surisuri Stone because I myself have experienced anxiety disorder, hyperventilation, and panic attacks. Of course, this alone will not eliminate all anxiety. However, I hope it will become a product that can be close to those who want to have a sense of security in their hands. For a change of pace during work, For a little healing while shopping or walking around town, When relaxing at home, Please use the Surisuri Stone in various situations. * For those who use it at home or want to put it in their pocket or bag, we can also make it without a string. Because it is newly made, the pattern and color will be your original, different from the photos. Please contact us. * Due to the nature of the material, many air bubbles are present.
