The knobs are chunky enough that my 1-year-old can actually grip them herself, which is rare for these puzzles. She's mostly just chewing on the pieces right now, but the rubberwood feels solid and the dyes haven't rubbed off at all.

My two-year-old figured out the color-coded base on her own within a day, which surprised me. The rubberwood feels solid and the low-VOC dye was a big reason I picked this over cheaper painted puzzles.

The chunky knobs are perfect for my 18-month-old's grip, and she actually gets the shapes in the right spots now. I like that the dyes are low VOC since she still puts everything in her mouth.
