I have been addicted to Washi tapes since they first came out. I absolutely love them! I am 70, so it is not only the younger generation. I use them on envelopes everytime I send something in the mail, I love to write letters and send cards. The Washi tapes come in so, so many different designs and colors, the choice is endless! They are also great on parcels, for scrapbooking ,,on plastic containers to give them an omph! I will continue to buy them and use them....they stick well and give a nice cheery look to everything you put them on.
