In a display at the Iceland National Museum there was a display which included Ringed Pins. An explanation at the display explained:
“Bronze Ringed Pins and others made of bone are found in both male and female graves; these were used as fasteners for clothes, as buttons had not been introduced for this purpose at this time, but merely as ornaments. Some have Celtic ornamentation, which indicates that they originate from the British Isles.”
The longest pin was probably 15-20 cm long
I’m guessing the shortest pin might be about 10 cm long.
