This is the materials list you will need to make your keychain:
- 01 large flat carabiner;
- 01 large key ring;
- 01 medium key ring;
- 03 opened iron rings;
- 01 standard carabiner;
- 01 meter (3.28 feet) chain.
You also need a plier to open and close the iron rings, but if you are so strong to do it with your hands, forget the pliers!
A NOTE FOR THE FLAT CARABINER: The flat carabiner is also called "table style" carabiner here in Brazil. I don't know how it is called outside here, but I include a pic of it here. Also, this model was choosed only because it is similar to the original model and anyone of your choice will work fine!
