These patterned key chain fobs are great by themselves or you can add a decal using HTV.
The patterned part is 5" x 0.75" (6 inches total including metal key ring).
If you are not ordering this product as an "add-on" with vinyl, shipping will not be accurate. I will reimburse you any overage charges based on real-time USPS rates for a smaller package.
Look for other items in matching patterns...can koozies, wine koozies, steering wheel covers etc.
