Please read my profile before considering a purchase. This is a paper book. It contains 20 sheets of paper, with 5 sheets each of 4 different types. A template for envelopes is included, so you can make envelopes with other paper as well. It can also be used for wrapping and decoration. I bought it but didn't use it and have stored it for a long time. Height: 21.1 cm, Width: 29.7 cm
