Previously, there was a negative pressure erection assistance device called "VCD-style Kanki" approved by the Ministry of Health, Labour and Welfare, but production has now ended. Therefore, because the rubber packing became unavailable, we requested production starting from the mold. The material is safe even if a baby licks it. It is an eco-friendly type that is reusable after washing, not disposable. We will sell according to the required quantity. We allow 4-7 days for shipping, but please message us if you need it urgently. *The main body is not sold.
