This bundle includes three packs of GHS GBTNT Boomers 10-52 strings. 

From the manufacturer: This is our latest twist on our classic Boomers® line. We begin with the finest nickel plated steel wire and coat it using a finely regulated process. This unique technology coats the outer wires which are then wrapped around a high quality core wire producing a string that has outstanding extended performance life with powerful tone. The plain steel strings are also coated to give a well balanced feel.
