Thank you for viewing. I am selling a collection of strings to be used for practice. They have been stored in a dark closet. They appear to be free of discoloration or rust, but please understand that this is based on a visual inspection and there may be issues I have missed. Please purchase with the understanding of this. The photos show everything, so please check them and consider your purchase. I am also selling on other flea market sites, so if there are simultaneous purchases, the first buyer will be prioritized, and I may have to delete the listing. Thank you for your understanding.
