The hollow chain does not break easily under normal wear but it is definitely not as strong as a solid gold chain. Hollow chains are not made to be worn with pendants, they are made to be only worn by themselves, so if you are looking to wear your chain with a pendant please consider purchasing a solid Miami Cuban Link chain such as https://www.itshot.com/luxurman-solid-14k-gold-cuban-link-chain-for-men-miami-5mm-wide or if it is out of your budget please take a look at this chain which is a similar style to Cuban link but it not as heavy (links are not as "fat" as in Miami Cuban Link chain): https://www.itshot.com/luxurman-solid-14k-gold-cuban-link-chain-for-men-miami-5mm-wide
