I bought some of these a while back to restring my magic and they worked out very well. they are high quality and very cheap.

These strings are high quality, durable, and come at really nice price. They work really well for restringing your broken magic or making custom magics. This was the best deal for magic strings I could find, and I am beyond satisfied with my purchase.
However, be aware that these strings can break if you go rough on your magic. The strings can withstand moderate use just like any other magic strings.
