Everything was packaged beautifully and arrived safely AND quickly. I was a bit worried about things like acrylic clips being in pieces when they showed up, but I had 0 problems. The staff communicates quickly and efficiently, which I greatly appreciate as a compulsive shopper. 🫡 The items are all of top quality, no Temu or AliBaba sh!t, and I'm so happy to have them in my collection. Thanks so much! 🌻
