I love the fact that they have a candy-shaped mini eraser inside, and that the envelope won't wear out as fast as the ones made of paper. The only thing I didn't like is that, in the blue one, you can't see the mini eraser from the outside.

Español:
Me encanta que tengan una mini-goma (borrador) con forma de caramelo adentro, y que la envoltura no se desgastará tan rápido como las de papel. Lo único que no me gustó es que, en la azul, no se puede ver la mini-goma desde afuera.
