My God, it’s full of stars! Yes it is. These star-filled envelopes will let you send an entire galaxy to your friends and loved ones. All they have to do is pour the contents out and look inside.
As long as your friend doesn’t tear it to shreds, they will have a fun geeky treat once they hold it up to a light source and see an astronomically-accurate group of constellations. Maybe your friend lives in the city and has never seen stars before or maybe they are a space geek. Either way, this is a great excuse to send a letter via snail mail.
You can buy a package of five from Japan Trend Shop, just be aware that this awesome product is ridiculously expensive. They will charge you $83(USD), plus the cost of shipping. The other alternative is to buy them directly from the Kaminokousakujo’s online store in Japan for about $10. Having them delivered to North America is something you will have to figure out yourself.
