Do you make your own plum blossom bookmarks, use the kind of real plants, buy your own outer plastic film, or find someone to plastic seal them? Do you know plastic?

Of course, you can do it yourself, provided that there are plastic films and they are sold in larger stationery wholesale stores. A hundred dollars costs a few dollars. It's expensive to find someone to do it. Just iron clothes with an iron, not steam. In order to prevent the plastic packaging film from curling and surface abrasion, the petals are sandwiched between several layers of paper and ironed with an iron. Try it several times, grasp the appropriate temperature, it will not be worse than the plastic packaging machine, and it can also be produced in large quantities, which can reduce a lot of costs. Don't press the whole. Push it from side to side. You can seal not only bookmarks, but also photos. If you can't press the edge, you can iron it again along the edge.
