And some people said lifespan does not apply in my case since I dropped glass and caused cracking.
Today, I have contacted to insurance company. She said there is lifespan if the 洗面台 is new one, the value of its is 100% but if it has been 10-15 years, it is not same as new one, since it is used.
It depends on the contract what I signed;however normal case is just what the insurance company case including mine too.
So if there are experiencing same case as like me, check my case but I have 火災保険、家財保険.
