Pin backs inadequate

Whilst the acrylic is printed and cut to a high standard the pin backs themselves are just stuck on with a foam sticker which is nowhere near strong enough to hold a pin if it's used on a bag or jacket as it's far too flimsy. The pics on the website make it look like the back is properly attached. I removed (easily) the foam stickers and restuck the backs with jewellers cement but it has caused cracks in the image on half of them unfortunately. Until the backs are stuck on better I will pass buying pins from here in future.
