United StatesGreat product.
The craftsmanship is absolutely top-notch — solid, heavy-duty, and built to last. You can tell this isn’t mass-produced — it has character and quality you just don’t find in most hardware these days. Highly recommend this product to anyone looking to add a timeless, handcrafted accent to their home. Worth every penny!

United StatesGreat 6th Anniversary Gift
The sweet bird feeder is adorable! It’ll look lovely in the garden and it will serve as a feeder for our feathered friends over the years. I purchased it as a 6th anniversary gift for our daughter and her husband, since iron is the traditional gift for 6 years of marriage.

I haven’t received it yet but trust they will be better than I imagine.

United StatesBeautiful Craftmanship
I ordered the 4" x 20" which arrived quickly. This works well for Coonhound and the Great Dane who both slap a paw on the door to come in. It is more substantial than ones ordered several years ago from another company. Well worth the money and I will order again.

We’re so glad it’s standing up to some serious paw power—those sound like some mighty door slappers! Thank you for the kind words, and we’d be honored to make more for you when the time comes.
