I've used this sort of thing for a while now (for neff crew primarily) and thought it would be a good idea to offer them up.
Two sizes available (20mm & 25mm) and they are cut from 0.8mm white beech veneer. The plank spacing is 4mm and there are ten per pack. Custom sizes are also available, please email or message for more info
