Our story

The most unique party stylist in St. Barth & the Caribbean

A party store like no other

We are Happy Days: the balloon stylists and all-inclusive party store based on the breathtakingly beautiful island of Saint Barthélemy in the heart of the Caribbean. Using balloons as art, we style and decorate every occasion imaginable, from birthdays to anniversaries to New Years and much more. Not only that, our online party store sells directly in St. Barth and ships worldwide to bring the best-quality party accessories and balloons items directly to you.

From a St. Barth dream, to a global reality

We work with only the best quality party brands: Talking Tables, Meri Meri, Ginger Ray and much more.
We are commited to ensuring all our work is sustainable and in consideration for the environment.
Exceptional support
Our international team provides the luxury of a modern shopping with traditional customer service at heart.
Caribbean beauty
The natural beauty of St. Barths provides the most beautiful back-drop to any balloon decorations.
At Happy Days, we are on a mission to redefine what it means to party. Turning every party dream into a reality and transforming life's celebrations into visions of color and beauty.
In 2019, Happy Days spent 3 months in New York City with its own pop-up store!
Our love for balloons
Balloons in bright colors of pink, gold or blue, floating in the air create a beautiful vision and adds that touch of magic to your party experience. With balloons any color, shape, size, vision or dream is possible. With Happy Days, we take the definition of a balloon to a whole new level and turn it into art.
