A glass "pocket hug" on a card is a small, heartfelt keepsake designed to provide comfort and a physical sense of connection when you are apart from a loved one. The tiny glass token, often shaped like a heart, is usually handmade and attached to a card with a sweet, supportive message or poem. The recipient can easily detach the smooth token and carry it in their pocket, offering a small, tangible reminder that someone cares and is thinking of them.
