You will not be receiving a large roll of Parafilm!!! I should warn you that the USPS sucks! I have to use them to keep costs down but, for the last year or two, their service has gotten really bad. I’ve been having more problems with items taking way longer than they should to get to my customers. I apologize but it is out of my control! If there is an issue, I’ll work with you to fix it. Please don’t automatically submit a complaint or negative review. This really hurts my business in the long run. Thank you for being so understanding.
