This (to a degree) is totally normal! Our Creatives Calendar® is different than a traditional white board, which we love for many reasons! Compared to the white boards you'd find in a store, they wipe cleaner, are lighter than their metal counterparts, and look a bit fancier. They are customizable to your liking, and made right here in the US! However, it won't give you the exact same look as a printed, flat piece of white board material. Because the calendars are topped with plexiglass, and because the sheets on the bigger sizes are so large, it's possible that there might be some flexing of the material – there would be no way for us to ensure entirely that this won't ever happen. It's mostly caused by a slight variation in humidity levels and temperatures, as well as the release of static electricity over times. (Sometimes, it helps to simply wipe the calendar, so that the static electricity sticks the plexi back closer to the paper).
If your plexi is pulled off of the calendar print more than .25" of an inch, and it's bothering you, please contact us at firstname.lastname@example.org and we'll work towards a solution!
