[Development period "2 years"] After accumulating improvements based on numerous failures, the leather shoe spatula was finally completed.　With the cooperation of Italian leather craftsmen and the opinions of businessmen, we were particular about leather and thoroughly committed to function and structure. [Carefully selected leather] First of all, we were very particular about the choice of materials. Italian leather carefully selected by leather craftsmen is luxuriously used. You can experience the original scent and smooth feel of leather. In addition, because it is the finest leather of natural tanning, you can feel the change in the expression of the leather.　The longer you use it, the more you can enjoy the change in the expression of the leather. [Thorough strength test] One of the opinions I often hear from businessmen is that they are not strong enough or that they are crooked.　It's a shock when your favorite shoehorn bends. BLUE SINCERE shoehorns are tested by a fair institution in Japan and use only materials that have cleared the standards. [Commitment to ease of use] Because it is used every day, we are thoroughly committed to ease of use. "I want to carry it with my keys," so we adopted a three-row key ring. It can also be used as a keychain.　 In addition, we are thoroughly particular about thinness, and have achieved a whopping 0.5 cm. Even if you put it in the breast pocket of your suit, it will not get in the way. By putting it in your breast pocket, you can quickly take it out and put on your shoes smartly.
