Since the very beginning, SPARROWS has always made it possible for you to add to your sets in a way that will ensure you do not end up with doubles or useless picks you do not want to own. The majority of SPARROWS sets also come with cases that have extra room allowing you to expand your collection and still fit all your tools in the same case. From Engraved to varying widths SPARROWS has a wide range of picks all available for single purchase.
