It has a 5mm width and a moderate sense of weight. The 60cm length is convenient as it can be put on and taken off over the head without removing the hook.

Of course, it is also suitable for those who do not have allergies, and can be used with peace of mind even when sweating during work or sports (please understand that even medical-grade stainless steel does not guarantee 100% allergy protection).
