The tracing pages are thick enough that my 4-year-old's marker doesn't bleed through, which honestly surprised me at this price. I handed these out as party favors and several parents texted me later asking where I got them.
Bought a stack of these for my daughter's kindergarten class and the tracing pages are perfect for her kids who are still learning pencil control. The coloring sections are simple enough that nobody gets frustrated, and the bulk pack means I didn't have to hunt down extras.
