Thank you for your interest getting the word out about digital book boxes! This is quite a departure from the physical book boxes we are familiar with, but may be more more accessible for both authors and readers, as well as potentially creating less waste.
It is by no means a requirement, but if you're willing to make a video sharing your experience, that might go a long way toward normalizing digital book boxes and spreading the word to other authors and readers who might actually prefer options like this one!
