>>48446344Updating on this, here's my whole current set. I'm migrating them around right now anyway so it's the perfect time to do this.
>>48447629The Pokemon Center pins are pretty nice quality, but most every one of them is single stemmed which is annoying for display. Lunala has 2 stems but they're right next to each other and I literally don't know why.
My personal favorite fanmade set is from ParadoxFox on Etsy. High quality double stemmed pins with a lot of Pokemon available. Would honestly recommend them over the center pins.
