If you have seen a product in our store that makes you especially excited that we add it to your surprise box, you just have to say so :)
Leave a comment in the comments field that you will find in the shopping cart, just below the total and before the confirm order button.
Please note that the product you choose may not fit in the box, either because of size or value. Example: You want us to put an A4 folder in the surprise box (the surprise boxes are smaller). Or you want to put a notebook that costs €15 in the small surprise box (we could hardly put anything else anymore).
In any case, we will contact you if we need any clarification.
