I made these beautiful bookmarks for my giftee and was planning to mail them - just regular old mail by putting it a envelope and put it out in the mail but they have beads in them and according to people online they will get ruined in the processing machines. Is this true? Should I mail them anyways or go ahead and ship them? I don’t want my bookmarks to get ruined and my giftee to end up with a letter full of broken parts. But I don’t know if there’s enough weight to them to really spend a lot of money on a big shipping box. Any ideas on what to do? I have some more flat bookmarks that will be okay in the mail but was hoping to include the bead ones as well
