Not sure how many of you still write letter and send by mail. If you do then you probably shouldn’t miss this post, where we will introduce you three creative and cool envelopes designed by a Japanese innovative company D-BROS. Most envelopes we use are quite plain: they are boring to look at and have no fun to tear it. D-BROS Booooon Envelopes are different. Coming in three designs: airplane, car, and locomotive. Beside each automobile is a small flap with the text “open” on it. When you tear open the envelope, the torn paper will leave a long trail and look like smoke behind those automobile. It is not only easy to open but fun to open as well.
