Perfect gift for any occasion! I chose the "special delivery" envelopes because me and my best friend write letters/send care packages to each other regularly. So mail is kind of special to us. This gift is for our 6 year friendship anniversary. I got blank envelopes to write my own messages. Every thing was packaged perfectly and safely. The jar is glass but it comes in a nice box with plenty of bubble wrap. Delivery was quicker than I expected. Overall I am highly satisfied and I WILL buy again!
