-Details- Unused, 2 sets Phosphor bronze color 011 015 022 032 042 052 Each set of 6 strings is individually packaged in a zip-lock bag. These are generic, overseas products, so there may be some slight imperfections or individual differences due to the manufacturing process. Also, there are no markings or labels for strings like 1st string or 2nd string, so you will need to distinguish them by the subtle differences in thickness. The gauge sizes are listed based on information provided by the seller. We have not performed any precise measurements or calculations, so if you are particular about the size, please purchase from a manufacturer or other sellers. We kindly request that you refrain from purchasing if you do not understand the nature of the product, or from transactions intended for complaints or unfair criticisms. We also have several other musical instrument-related products for sale. We would be grateful if you would take a look if you are interested. #penguin_musical_instruments -Shipping Method- Yu-packet Post Mini (anonymous shipping) We will ship with simple packaging without using cushioning material.
