Printed key chains are usually printed on stainless iron, bronze or aluminum. They can be silk screen or offset printed. The finished product needs to be coated with epoxy to protect the ink from being wiped off. Because the price is very advantageous and the production speed is fast, it can be used as promotional items for businesses, providing a cost-effective and practical way to increase brand visibility. At the same time, printing can achieve rich colors, which greatly maintains the degree of restoration of the customized LOGO.
