    "I drop my smartphone and break it..." "Using a smartphone makes my posture worse..." "Smartphone rings are too big..." "It's hard to find a ring for my tablet..." For those who want to We offer "SYANTO" in genuine leather!

    This is a sheet-type ring that is inserted between the smartphone and the case. By holding it with your little finger, you prevent the risk of dropping your smartphone. Since it is a sheet type, it has a compact design with excellent retention and operability compared to general rings. Additionally, by attaching the seat to the bottom, you can support your smartphone with your entire hand, which helps prevent bad posture. We have developed this product as a product that can reduce the problems of dropping and damaging your smartphone and worrying about your posture when using it.

    screen angle

    If the smartphone screen is horizontal, the angle of the neck will also be more likely to be horizontal. When the angle of the screen becomes vertical, your posture will naturally occur. The angle of the screen and the angle of your neck are proportional.

    When using SYANTO, the viewpoint is at the bottom of the smartphone , which naturally increases the angle of the screen, making it easier to stand up.

    don't hold it

    If you hold your smartphone in your hand, your posture will curl up. If you hold your smartphone on it , your posture and neck will be shunted.

    little finger

    Traditional smartphone rings are held by holding them with your index finger . Your index finger is connected to your stomach, so if you grip it with your index finger, it will put pressure on your stomach and make it easier to curl up. However, SYANTO uses your little finger and engages your back muscles, making it easier to get upright. In addition, the little finger, back, shoulder blades, and other parts of the body are linked together. This will make your smartphone or tablet feel lighter.

    ``SYANTO'' prevents your smartphone from slipping off by inserting your finger into the ring on the bottom . In addition, the stable hold achieved by utilizing the little finger on the bottom support prevents the smartphone from falling and damaging it.

    You can take it out smartly even from pockets that are difficult to take out.

    Unlike smartphone rings that attach to the back, the back of the smartphone is flat, so there is no effect on wireless charging.

    This smartphone, which you touch many times every day, is made of genuine cow and sheep leather that is gentle on your hands and durable. Unlike synthetic leather products, we aim to create a look that will retain its flavor over time.
