It's okay just not like the proof.

I purposely chose the colors so that the black silhouettes stood out on the grey background but when I received the coasters I can barely see them, they only show if there's glare. The rest of the colours are fine so I'm unsure what happened. I'm not sure why I'm given a proof to review if the print will not look like the proof. This is the second time this has happened to me (last time it was shipping packages) and although I appreciate discounts, I'd appreciate if the quality still would be the same as a non-discounted purchase. Sticker Mule has been great to me before but these last two purchase have fallen flat, I feel bad leaving a negative review but I want to be candid.
