Inspired, connected, sleek and beautiful - there’s a million reasons and places for a Heartstrings’ Interval Keychain. The quality stainless steel key ring is electrified with eye-catching electric bass guitar string and elegantly punctuated with a ball end.

The Interval Keychain is available in traditional silver bass guitar string with a gold or silver ball end or, through Heartstrings’ innovative in-house coating process, metallic blue and electra grey.

The coating gradually thins over time, presenting as a patina that allows the silver undertones to shine through. 

Heartstrings’ eco-friendly promise delivers jewelry and packaging that transform retired materials into beauty for even the most discerning.
