Close bag perfectly
I have already tried everything possible to close open bags, bags, bags etc. There are these rails that you can push through, or you can try it with paper clips or those pouch closures that are on the toast package. Everything somehow unwieldy.
By chance, I found letterpress. They come in different sizes and you can simply clamp them on the opened package. Simply fold over the top edge once or twice and lock it up. Keeps great and does not annoy when reopening.
