Let customers speak for us
It’s beautifully done im afraid to put it on the car lol
The magnet came out PERFECT
Fantastic quality, perfectly quirky. i am proud to display these on my vehicles
Great bumper magnet! Not sure what to haul with this trailer anymore though…
I like the design, wish I got it in magnet form instead of stickers like the rest of my order :)
Product as advertised. Actually got two, probably inadverently.
These are the best ones ive seen in awhile, will definitely be buying more
Great quality magnet and printing. Fast shipping and excellent customer service
Had some delays shipping but they made it right for me. Bought the magnets to prank a friend of mine. Secretly slipped them on and allowed her to find them on her car later. It worked beautifully.
Has not disappointed me at all. Strong magnet.
Perfect. Just what I wanted (and needed). Have caught people laughing at it in my rearview mirror.
Sticker magnet is in good quality! Very surprised with how well it sticks on a car.
