High Quality Product for Effective Guerilla Marketing

I placed my order for these magnets with a little hesitation. I needed "refrigerator magnets" to put into action an idea a Canadian businessman told me about while I was vacationing in Belize: put promotional magnets on a business vehicle that invite the public to take one so that your company rigs are distributing "business cards" while they're parked. a 4x2.5" magnet is not a lot of "real estate" to work with, I have a complicated logo/motto I've been using for over a decade, and I wanted to include a QR code. The graphics quality had to be top notch, but having never ordered these from Sticker Mule before I didn't know what they were capable of producing, hence my initial hesitancy. The magnets that I received exceeded my most optimistic expectations! The graphics are sharp, the text is clear, and I've managed to scan the QR code with my phone held at 12" away from the magnet, far farther away than how people will typically interact with these in "the real world". I've also "torture tested" the magnets on the side of my vehicle travelling at 70mph - they've all held on! If this idea takes off, I will be buying more of these magnets in the future.
