A review for Circle stickers by Andy Hunt.
The stickers seem to be of good quality but there was some bleeding or smudging of the black in to the white areas. also, I they had a matte finish which was fine but not expected or disclosed prior to purchase. I don't recall being offered a choice but I could've missed it.
After posting the review Sticker Mule reached out to me personally to find out more. They seem genuinely concerned with any potential problems with their product and are very responsive via email. Changed from "so-so" to "smile" star for A+ customer service.
