Ok ... so not being tight but I do think £60+ for 5 pairs of Westfalia tie backs is somewhat over the top .... I've found some silicone rubber strip .... So thought I'd share the link here I've gone for 20mm x 1.5mm for the grand total of £13 for 5m https://shop.deltarubber.co.uk/rubber-strip/silicone-rubber-strip/white-silicone-rubber-strip.html
I made these.... From these... Sure there’s a white version of the belt. Just used a ‘pop stud’ kit from amazon.
