“It's a high-quality thimble, with an open top.
Beware that this thimble only comes in one size and, being brass, it is extremely hard and therefore difficult to manipulate if you want to squash it to fit your finger better.
The size is generous, as is the top opening, so if your fingers are on the larger side, you will be safe with this thimble.
However, if you are like me and have slim fingers, this will be difficult to squash to fit your middle finger (for reference my middle finger ring size is L/M, and my fingertip will be smaller still).
I can't fault its quality, though, and it looks very nice.”
