PostCarden designed by London based A Studio for Design is the perfect gift for any occasion. Earth Day is coming up next week so why not put a smile on someone’s face with a green card. It arrives in the mail just like any other postcard. Only once you have read the message it doesn’t turn into a static object to pin on the kitchen board, but it unfolds into a pop-up garden. It comes with instructions and cress seeds that after a few days will start growing and will last two to three weeks. Simply follow the instructions and place somewhere warm with plenty of light for best results. PostCarden is a great gifts for any age group, grown-ups and children alike. Kids in particular will enjoy following the development of the seeds into little cress plants.  PostCarden is a completely British product. It is printed in Wales by Ethical Packaging and the seeds are also sourced nationally.
