I like simple designs, and I create works that are easy to use and timeless, with a touch of cuteness (*^_^*) , as the image comes to mind. I would be happy if those who share the same sensibilities could appreciate my work (*^_^*) This is a handmade product, so it is not as perfect as a mass-produced item (^◇^;) Please understand that it has a unique charm that you won't find anywhere else. Although it is amateur work, I make it with care. Please understand that there may be scratches or slight stains on the leather during the production process. There are no smokers, but I have a cat. Please understand that there may be cat hair on the product. The colors in the photos may differ slightly from the actual product due to lighting conditions, etc. Please understand.
