"Bought these before- they keep clasped for a while, but sometimes they'll fall off after a few weeks :/ packaged well, got a sticker with it- pin backings came in a plastic easy-open bag, but last time I ordered, they were in a cute ribbon drawbag. Either way, they work well and happy to have more :)"
