These <b>Synthetic core strings</b> are of medium tension, optimized for most players! Each string is individually packed and sealed to protect from corrosion. <br> <br> When compared to the world's most popular strings ( <b>Thomastik Dominant</b>), none of our professionals could tell them apart. Just like the Dominant strings, they are warm and resemble gut strings (while being way more resistant to humidity). They are soft, clear, and rich in overtones. But the best part, they're half the price of Dominants!
