The upgraded version of Twin-barrel pencil sharpener features an advanced two-step sharpening system. This two-step sharpening system first sharpens the wood and then sharpens a pencil's graphite core precisely. It holds the same amount of shavings as its previous version and after upgrading, the lid will stay shut when you use it. The rubberised body will provide an extra grip when you twist your pencil in it. It also features a sleek matte finish.
