Query: Horrible Glue on Decent Package

This is my first review on Amazon as I felt I needed to warn other users about this product.I use padded mailers at home regularly and have used a variety of products.Pros:1) Bubble wrap inside mailer is great quality2) Outside of mailer is strongCons:1) Glue on mailers is HORRIBLE. 1 out of 10 of the mailers have glue that works. The others, the glue either sticks to cover when it is removed instead of to the mailer or rips off the glue and part of the mailer.2) Size is tighter than other mailers so larger books won't fit inside.Due to the poor quality of glue used in this product, I will not be ordering these mailers again.
