Most married men want the message out there that they’re taken. The best way to do this is to wear a wedding ring. Some, however, work in harsh conditions where any expensive ring may be damaged. In this situation, the Rhino Ring comes to the rescue. This is a synthetic ring made of rubber to be worn just like a wedding ring. It’s durable enough to withstand hazardous environments, while still getting the message out to stay away. The ring looks like any traditional band and is a cool way for rugged married men to maintain their marital commitments. One costs backers $10 with a campaign goal on Kickstarter of $1,800.
