100cm length of elastic - white 100cm length of boilproof elastic - white £0.40 inc. VAT Out of stock. I've been making face coverings using the brilliant pattern from Dhurata Davies When I looked for elastic it quickly became clear that there are a lot of folk asking silly money for something that costs pennies. This elastic is 8mm wide and is boilproof. Maximum of 8 meters per order please. If you order more than one meter the elastic will be sent as one length.
