It saddens me to say, these buttons are awful. This is the very first time I placed an order and am not pleased with outcome. All my previous orders were spot on perfect!!
When you try to adjust pin to correct position, in palm of hand or otherwise, the entire silver back comes off and there is no getting it back on so it will stay. Super disappointing in the quality of this order. These pins were ordered in honor of someone who passed and I’m not going to be able to pass them out because of poor manufacturing. 
Really disappointed.
