Purchasing Gift Cards to give to friends or family? Instead of emailing an eCard directly to them, why not send it to yourself, print off, and place in one of our stylish 18 Clues Presentation Sleeves. A much classier way of presenting your Gifts of Adventure. We'll post the Presentation Sleeves out to you so you can insert the Gift Cards you have purchased and present to your friends or loved ones. All proceeds from the Presentation Sleeves will be donated to charity.
