Review: Great mailer bags and quality. My 2nd time purchasing these, but this time in black because they were on sale for a reasonable price and had prime shipping, I was disappointed the blue ones were not; didn't make sense. Thickness is pretty good, they're not see through so couldn't see what you're shipping. Adhesive seal is good, but I always go back and tape over seal for extra caution. These are easy to use, flexible, and functional. Love the size of these as well.
Review: Very heavy duty holds lots will buy again
