Review on πŸ” JSP Steel Ring Mandrel for Accurate Sizing by Gelin Battle

Revainrating 4 out of 5

Not sure if the size is one size?

Love this mandrel! I recently got into jewelry making and use it to make ring blanks. The steel is AMAZING because you can use a hammer right on it to measure the rings and it won't jingle! (Aluminum will be dented) My only concern is that I'm not sure of the exact sizing? I put my wedding ring on it to check the size and it says my ring is a size 3.75 when I was a size 4.

Pros
  • Durable test results
Cons
  • Could have chosen a newer model
