You can still work with the pages while you're waiting for the binder to arrive.
It seems to take ages for things to arrive. I ordered some speaker crossover air core inductors back in February (
https://www.parts-express.com/crossover-inductors-table), from a well established supplier and they backordered them. Possibly to ship in July. That will be OK for me, because that is my timeline for getting my shop up and running again, but if you are in business and NEED this stuff now, you're screwed.
Hope your stamp hobby is giving you joy!
BUT, mail order succes ordering pants, and they fit, is really cool. Shoes is as close as I have come lately and I had ordered the exact same shoes I had before, using the inner labels to identify.
