Prim – Swedish perfection in strings since the 1940s

Prim Strings is a renowned Swedish family business that has been producing high-quality strings for violin, viola, cello, and double bass since the 1940s. What began as a personal quest for better sound quality has grown into a globally respected brand, beloved for its reliability, clarity, and durability . Prim strings are still developed and manufactured in Sweden, with a focus on natural tone, precision, and traditional Scandinavian craftsmanship .

The beginning of Prim Strings

Prim's origins date back to the early 1940s, when Gunnar Fröjel , a passionate cellist from Stockholm, struggled to obtain good strings during World War II. In his quest for quality, he decided to make his own—first in his own kitchen, with the help of his wife, who literally acted as the driving force behind the production process. The results were so good that fellow musicians soon showed interest, and thus Prim Strings was born.

What began as a small-scale craft quickly grew into a successful company in Stockholm. Thanks to an early, internationally registered patent application, Prim distinguished itself as one of the first modern manufacturers to apply innovative technology to the production of metal strings.

Generations of innovation

In 1981 , Urban Fröjel , the founder's son, took over the company. Under his leadership, Prim was further industrialized without losing its characteristic tone quality. Urban introduced new string types, refined production methods, and expanded international exports—resulting in Prim strings becoming a household name worldwide.

In 1994, the company moved to a new, more modern production facility, where the focus was on consistency, precision, and sustainable quality control. Since 2015 , the third generation has been active: Niclas and Jessica Fröjel , Urban's children, continue the family tradition. Today, Niclas Fröjel leads the company and focuses on developing the next generation of strings, with even better playing response and a wider dynamic range.
