All EINSEO products are fully waterproof! Safe for water cleaning and shower/bath use. Avoid prolonged soaking.

For masturbation devices, make sure to clean and dry them thoroughly. You may use a renewal powder (such as cornstarch or toy powder) afterward to help maintain the material and prolong its lifespan.

The materials used in our toys are skin-safe and body-friendly. Please do not use alcohol to disinfect, as it may cause the surface to discolor. Also, do not boil the products, as high temperatures can damage internal components like motors.

For most products like masturbators or smaller products, charging time may exceed 120 minutes. While charging, the indicator light will flash repeatedly; when fully charged, the indicator light will stay on.

Additionally, if you are charging the toy after cleaning it, please ensure that the charging port is dry before charging.

Always use a water-based lubricant before and during use. This helps reduce friction and ensures a smoother, more comfortable experience. Avoid using silicone-based or oil-based lubricants, as they may degrade or damage the toy’s material. Apply lubricant generously to both the toy and your body, and if you're using the toy for an extended period, reapply every10–15 minutesto maintain smoothness. If you feel pain, resistance, or notice any bleeding, stop using the product immediately and seek medical advice if needed.
