Review on 📦 Transparent Self-Adhesive Shipping Envelopes by Jose Mcdaniel

I work in a medical laboratory where we occasionally send samples to other (reference) laboratories. Our current supplier has started charging ridiculous prices for 20 pack mailer/packaging bags. We ordered these which will last us at least a few months. The package stays and we have no problem scanning the labels inside. We didn't lose a single copy in transit so it does the job.
