But unfortunately well finished no way to store the pen

The bag is made very valuable and the Surface Pro 3 fits well, including the Type Cover, though a bit tight inside. Since the case has been handmade especially for the Surface Pro 3, I assumed that there is a small tab or a small compartment etc for the standard package of the Surface Pro 3 belonging pin. Unfortunately, not as much thought by the manufacturer. The pin therefore has no place. It can be loosely placed in the envelope and then flies around there :(
Who the pen is not as important will surely get a well-made and stylish casing. Unfortunately, the lack of accommodation option is so disturbing that I must deduct 2 points and will send the item back.
In general cases for tablets I would not complain. Who but advertises to have designed a cover for the Surface Pro 3, which should also please device for the pin with concerns. A small tab etc would have been enough.
