ban.do is a company that sells neat-looking things, including sticker books. On their website, as with many retailers, I like to search the word ‘rainbow’ and scroll through. Ahhhhhhhh that’s nice.
Generally, I prefer sticker books over sticker sheets for ease of use. It requires less thinking power to flip through a themed book and zone out, rather than sifting through. The ban.do issues are a nice compromise, since they are about 4” x 6” - portable enough to transport a few, rather than a huge tome of stickers. You can easily pull out a sheet to share without wrecking the booklet.
I can’t find Issue#1, but here are the covers of #2-9. They have varying availability. I have sets #5 and #7. They are very cartoony and cute! The earlier issues are more planner-oriented with duplicates, and the later ones are more varied. You can see some flip-throughs on YouTube.
Maybe it’s these? I truly have no idea.
