Give the gift of glass! If you have a flameworker in your life – this is the best gift ever. Gift certificates can be purchased in $25.00 increments. For example, choose 4 and we will provide you with a $100 certificate. Gift certificates will be emailed to you for you to print at home. Nortel gift certificates can only be used at Nortel in Toronto, or on our website. We are unable to offer them for use through any of our distributors.
