I bought it because I trusted the estimated shipping date of 1~2 days, but it took until 5 days before the cancellation request deadline.
Thanks to that, I was not able to use it in time for the event I had originally planned to use it for.
Maybe I just didn't notice the notice, but they should either keep the shipping date or correct it.
Because it arrived so late, I checked the postmark and found that it was four days after the shipping notice was given.
At least three days after the shipping notice was sent out, the mail was posted.
