I could see linking to some photos of the first edition. There's a few images, but since you've printed a batch already, seeing photos of those might make it feel more real and more useful.

Also, if any buyers of the first batch posted public, verifiable comments about the cards or how they used them (like on Twitter or Instagram), I could see inlining those.

Hi HN fellows, it’s the author here. One of the most rewarding experiences in the past year was to show people different psychological concepts and how to use them to understand themselves and others. This inspired me to design this set of cards. Easy to understand concepts, illuminating examples and simple explanations.

One thing I had in mind was to help parents teach kids about their emotions, for example. However, because I struggle with anxiety, I found it important to make them in physical form, to help me focus on their texture and shape, whenever I feel the need to ground myself.

Long story short, it was an amazing experience creating them and I’m happy to share with you anything you would like to know.
