*We do not deliver to private residences (detached houses or apartment buildings). *Depending on the delivery location, the delivery date may be delayed and additional shipping charges may apply. *Do not use for purposes other than its intended use. Do not inflate more air than necessary. When setting it in the sleeve hole, check that there are no protrusions on the surface of the hole. When inflating, insert it straight and be careful not to break the rubber wall. This product alone may not completely stop water leakage, so use sealant if necessary. In particular, if the air pump tube has a diameter of 100mm or less, this product may not inflate completely, causing wrinkles and leakage.
