UPS Shipping Materials (Pratt Institute-Myrtle Avenue)

I have various UPS shipping boxes, padded mailers, and envelopes for free. Too much to take pictures. I was running a business but ordered too many supplies that I don't need. All new. Never used. Otherwise, I will have to recycle them. I hate to throw them away. Been a hit and miss trying to give them to a UPS truck driver. UPS Customer Service said I could do that. The UPS Stores don't take UPS materials back.
