Bright and bold assorted colours. Staedtler 175 is a wood-free colouring pencil constructed from synthetic resin. Synthetic resin does not leave splinters in the mouth when chewed and does not splinter when snapped. The velvety soft lead transfers onto paper smoothly. The colours are bright and bold. The pencils are easy to sharpen to a consistent sharp point, helping children enjoy their colouring fuss-free. The non-slip rubberised surface also makes the pencil more comfortable to hold.
