21 Day Necklace


Studies show that it takes 21 days to make or break a habit. We have developed this necklace to help you get to day 21.

Once you receive your 21 Day Necklace, we suggest that you write out your goal on a piece of paper: "Start with the end in mind."

Every 3 days you have stayed the course, you will add 1 brass disc to your shackle necklace. (Each disc is stamped with day 1-3, 4-6, etc… up to day 21). Each brass disc not only represents the work you have completed, but they also show you how much closer you are creating a lasting habit.

Only when you have filled your necklace do we encourage you to tell friends about what you have accomplished.

ESSE QUAM VIDERI “To be, rather than to seem."

  • Brass shackle
  • 27” stainless ball chain necklace 
  • Cable holding all day-marker discs

Please note: All our brass pendants are raw brass, meaning they are not electroplated and will develop a beautiful patina over time. We recommend polishing it with a soft cloth to help keep your pendant's original shine if you prefer the bright metal look.


All of our customers are part of our crew, and we take care of our own. If you have any issues with your order, we will do everything we can to fix the problem.

Here at Maritime, we work hard to create an ethical work environment. With such a small staff, it is crucial that everyone feel valued and heard in the role they play in company structure. Our price points directly reflect the amount of effort, creativity, and hard work that go into each piece, and proceeds contribute to a living wage for our team.

21 Days to Good Habits

I just started wearing the 21 Day pendant on the same chain as my Memento Mori/Memento Vivere pendant. It’s going to help me start some new good habits and break a bad habit. Love the quality and craftsmanship.

Solid and made in the USA!

I do manual plumbing work, always in the dirt. I never take the necklace off unless to clean and polish it. Its been hit by pipe wrenches and lightly hung up on objects, been worn on an enduro bike going 55 mph down the highway, and it is still holding strong. The the harder outer finish will chip a little if worn in rugged places but the inherited wear shows more character. Will buy more Maritime products in the future. Also thank you for the quality products, Ill happily pay more for you guy’s products any day !
