Reuse or make your own bubble bags
You do not necessarily have to buy air bags (for example for book mailings) for a lot of money.
Either you use old ones again. To paste the address information, own very well package / parcel label of the post office.
If the envelope is still no longer useful, I separate the inner "bubble part" out.
Furthermore, I bought a large bubble wrap roll in the flower department for about 4 euros in the hardware store. Now bought from the 1 Euro-55-cent crate box shop and cheap envelopes / shipping bags in different sizes. Usually you have some of them at home anyway.
Now either old insert or cut a new one - maybe with a stapler make a bag out of it. Punch off in the edge of the envelope - clip in - done. Or just to glue ...
Mostly I reinforce the opening with a strip of Tesa before punching so it does not freak out.
So you save a lot of money and space, as a roll can be stored much easier than air cushion envelopes. In addition, I can customize the envelopes for each book, making them even safer.
I got rid of my old study literature on Ebay by now ...
Have fun tinkering - sounds more complicated than it is.
