String duration

March 18, 2026, 5:29 AM · Hi all,
I got a set of Pirastro Tonica viola strings for my birthday in Sep last year, and I put them on at the mid-end of Nov.
As I went to practise last night, the string at the scroll end has begun to fray/unravel. I was wondering what the general length of time they last for is?
I don't think I have had this problem with Tonica's before.

Thanks in advance.

I had problems with a two-month old Violino A string becoming unwound about an inch from the bridge. Contacted them with a photo, and they sent me a replacement string.
Amazing customer service.
