About this app
Craft envelopes and boxes in any size you want with the Envelope Punch Board. Just enter the size you want your envelope or box to be and the app will tell you how large your paper has to be and where you have to score and punch it. You can switch between inch and centimeter and also save your favorite envelopes and boxes for later.
