+1 on the 2021 Pass Around Box. It was 40+Lbs of fun.
Much appreciation to who ever will be making the new Aluminum box.
Note: USPS has more than one vendor making the "Medium" size Priority Mail boxes. They each vary slightly in size. It would be helpful if the new box was sized to fit the "smallest" medium size Priority Shipper.
When I last received the Pass Around box, I had to visit 3 different Post Offices until I found the "other" vendor's box and could get the Aluminum box to slide into it. ( This delayed me about a week in passing the box along.) There were a couple of posts from others that experienced the same, in the Old Pass Around Box thread.
