Craig & Stasia really helped out by reversing the polarities on these gorgeous black & white pattern design magnets so that I could attach them onto my flyscreen doors as fly screen savers (to stop people from walking into the doors - I thought people were just being clumsy until I did it myself a few times). The magnets look great, complement the industrial chic styling of my highly reviewed & very popular Airbnb AND they do the job very well. They adhere to the flyscreen strongly & their low profile means they do not get scraped off the door as it slides to & fro. So far even parents with kids have not been able to dislodge these babies! It means I do not have to be replacing flyscreen & door frames on a regular basis, not to mention eliminating the discomfort & embarassment of those walking into the door. Thx Craig & Stasia!
