I was very disappointed with Black Door. The envelope flap tore when I opened it. It is now
unusable. You are warned in the video about tearing, so I was very careful. I never thought it would
tear that easy. You can handle Kleenex rougher and it doesn’t tear. It is now in the throw away box,
another waste of money.
Agree, should have been made of Tyvek.
What I do now is, if I do not see the envelope based effect made of Tyvek, I will not purchase.
Words to live by.
