Very good size even if pen takes up space.
Possible to cut different sizes of pencils (mines) and different textures (graphite, pastel, lead, charcoal, color, etc.)
Can tighten the blades and / or change.
I could have put 4 stars but the fragile side of the opening / closing can quickly split into 2 pencil size. The opening reels also plays on the fragility of the opening / closing.
I recommend while chopant the hand for manipulation.
All ages
(Allows to prune large enough pencils for children)
