D’Addario Prelude Violin Single String, Single E String, 1/4 Scale, Medium Tension - J811 1/4M - Solid Steel Core, Warm Tone, Economical and Durable – Educator’s Choice for Student Strings – 1 String

I have a beginner kid who just got a 2nd hand violin. The younger sister was too curious to tune the violin and broke the E string. Thus, the mom, me, who doesn't know anything about violin, need to fix it. I googled and watched lots of YouTube videos, decided to purchase this an give it a try. Turns out it's not too hard. You need to make sure you buy the correct size and check the end. This one is a ball type. This is my first time playing with a violin, so I don't know about the sound quality stuff. But I can tell it sounds much better than the old one.
