I’d love to buy a pack of these but unfortunately I’m not much of a pen and paper guy. All of my notes and organization is done on my iPhone and honestly, I’d rather carry one thing than my iPhone and a small stack of these cards. My father on the other hand was always a huge fan of organizing his life with index cards and I’m sure he would have loved these.
My only real problem with these index cards is the name. I understand the idea behind the name, but I think a better name could have been found. And, it wouldn’t have the problem of being associated with other helveti-products.
