A review for Custom magnets by Chris Oldt.
I thought the printing and color quality of these were really great! Exactly what I'd hoped for. Unfortunately, most of them were unusable because they had black streaks running across them. I reported this and was told they'd get back to me with an explanation but still haven't. (10 days ago).
I'd say that if Stickermule can figure out how to keep this from happening again, I would gladly order magnets from them in the future. But until then I won't be able to.
