Pi Wax Seal
Add some vintage flair and your love of Pi to your stationary with this sealing wax kit. It’s also the perfect gift for the person who has everything! Each seal comes in its own kraft box with a stick of deep red mailable sealing wax with a wick for quick and easy use.
How to use this:
Light the wick and allow a pool of wax to collect on your envelope, then press the seal into the center of the pool (if it's hot out, it works best to chill the seal a bit) and your letter is secure!
