What matters in use
Catalog numbers tell only part of the story. These are the details most likely to change how this product feels, sounds, or fits into a setup.
Detail 01
One string, third from the top. The G, A and E are sold separately.
Detail 02
Sized for a full-size violin. Shorter fractional instruments need their own scale length.
Detail 03
High for a single middle string. Replacing all four this way adds up fast compared to a set.
Detail 04
The D carries much of the instrument's lower-middle voice, so a dead D is obvious before the outer strings go.
Detail 05
A fresh D next to three older strings will sound brighter and louder until the others are changed.

Product questions
Straight answers to the questions shoppers most often ask about this product.
One — the D string. The other three are separate purchases.
No. It is made for full-size, 4/4 violin only.
You can, and it is normal when one string fails early. The new D will stand out against older strings until you change the rest.
Expect frequent retuning for the first few days as the string stretches, then it holds pitch normally.
