Frequently asked questions
What is the maximum size of the contents?
The inner dimensions of 350 x 470 mm apply to flat items with no significant height. If your contents have real fill height, space gets tighter: the envelope has to bulge around them, which reduces the width and length. Rule of thumb: subtract the fill height plus 0.5 cm of clearance for sliding the item in from both the width and the length.
