Decent acrylic pins, fast production and shipping, quality control lacking

I’ve purchased pins from stickermule quite a few times over the past couple of years. Small runs of 50 pins each. Stickermule has fixed the issue with the sticker they used to use to hold the pin back on the acrylic. Must appreciated. However this time, I ordered a small run of just 10 pins. In general, when I order pins from anywhere, acrylic or enamel, there’s a few lower grade pins that make it into the batches, I understand that sometimes things happen. But when I only order 10 and one has THREE bad spots on it, it makes it so I cannot sell that one, so now I’m down a tenth of my inventory. I would think with such a small run, it wouldn’t be that difficult to make sure each one is perfect. :(
