My 4-year-old absolutely loves these flashcards! The illustrations are beautiful and the dual-side learning is brilliant. Quality is genuinely premium — much better than what we've seen elsewhere. Highly recommend to parents.

Product information
Advanced Montessori sensorial set for Indian children aged 3 to 6 years refining visual size discrimination. Four colour families of graded knobless wooden cylinders (red, yellow, green, blue) plus activity cards guide the child through sorting, stacking and pairing exercises. Comes after the knobbed Cylinder Block in the Montessori sequence: the same size-discrimination skill is now practised with free-hand grip instead of knob-tops.

Why curated by SkilloToys
We pick this set because once a child has mastered the knobbed Cylinder Block, the next refinement is to take the knob away. The knobless cylinders force the child to grip the cylinder body and compare sizes with even greater visual precision. The activity cards guide the work cycle so the child doesn't run out of ideas after the first sorting round.
