Quality is hit or miss

It pains me to write this because StcikerMule excels at stickers. I bought a batch of 10 pins last month and they were great. They had a sale for 50 and they arrived with quality issues such a glue residue, poor backing placement, etc. The replacement order arrive with the image not centered, some missing the pin backing, and some had chips in the image or plastic. I would look elsewhere for pins.
