What our customers say
Works great for my wall mounted mail box. Ideal size.
Strong and Durable!!! Looooove! After reading about similar products, I chose this one because it was fully rubber and did not have a paper layer.
I can't imagine a better buy. This was so easy. Thanks so much for this product. Really made my day!
This stick on flag was exactly what I was looking for. Very easy to install. I bought it to use on a group mailbox where I work.
Perfect Solution! When my mailbox was plowed over during a heavy New England blizzard, I thought I would have to pay for a new mailbox until I found this magnetic post flag replacement online. Perfect solution without the added costs.
