Duncan yo-yo replacement strings for all Duncan yo-yos. Cellophane package of two 100% Egyptian cotton strings for ten cents. From around 1961.
This blue string package version is hard to find, especially in this condition. Most are found with wrinkled paper, faded printing, and rips or tears in the paper from being stapled. The two-color printing of the overall design is often misaligned too. Compare with the Duncan red string package version from around 1963.
