Water Seal Contains water. The amount of water in the seals varies. Some seals do not contain water. We are not responsible for water leaks during shipping. They are prone to leaking. Due to being an overseas product, the inspection standards are more lenient than those in Japan, and there may be stains, scratches, printing errors, burrs, etc. Please refrain from purchasing if you are concerned about these issues. We will put them in an OPP bag and take measures to prevent water damage, but we will not provide any reinforcement. Please be aware of this.
