We recently came across the Bible in a spiral format. Wow! This is new to us. You can find a copy here: https://spiralbible.com/.
They are only available on this site in KJV, but the publisher says they will produce copies in other versions soon. They have one that is nicely illustrated for kids. According to their website, reading with a pen and marker improves focus and concentration and helps you organize your thoughts. This is something we can improve on!
