Probably the cheapest ranges for children on the market! There are 5 pieces in a pack, so children can choose their own color. The colors are beautiful and bright. The ruler is fairly flexible; I prefer hard (wood/stainless steel) for kids. It's more flexible than my Westcott acrylic ruler. The markings are clearly marked and legible. It's great that it's transparent so kids can see what's on the paper as they draw the lines.
