As a bracelet-feeling-enthusiast, this is such a great thread to read!
Since I don’t have a vacuum pump and don’t intend to get one for now, I had the following idea, and I wanted to ask in this round what you think about it. I have a sous vide device for the kitchen. Of course, it won’t be able to create the same pressure as such a pump, but it might have a similar effect. What do you think?
