Glad you asked Vintage. A length of string is relative to either A) The manufactured length as indicated at the point of sale. B) The length cut relative to perform the required task for which the product was engaged.
Or C) the length at which the string was broken or cut either during or post use. This length is indeterminate but always less than the length required at the point of original use.
I think I’m funny anyway?
Or (D), the string is still being manufactured as we speak in some Chinese sweatshop, a subsidiary of 5USports (operations currently on a slowdown due to staff being kept away to combat the Coronavirus), and grows daily to the point where a third warehouse has had to be erected in a record five day period of extensive construction work?
