1. Stand the upright vertically upon a sturdy table. Using the correct orientation, carefully slot the base-plate over the top of the upright and push down.
2. Turn the holder upside down. Using your thumbs, push the upright fully into the base-plate to ensure it's properly located.
3. Peel and align the adhesive felt to the underside of the base-plate. This pad will protect your table surface wherever you decide to use your spectacle holder.
