“Overall, this product is great for my needs but in the pack I received, half the self adhesive circles were stuck to the wrong side of the metal discs. They have a rough side and a shiny polished side��?for my work I need the shiny polished side to be visible but on half of them the self adhesive part was stuck onto the shiny side. This meant I had to faff about soaking them in acetone and scraping the sticky part off so that I could glue them down instead. If you are not bothered which side you need to be sticky then they are fine but if, like me, you need them to be shiny side up then it would be better if more care was taken during the quality control/packaging side of things before they are dispatched to customers.”
