This is an "pencil sharpener" type peeler that resembles a carrot as a "pencil". The usage is, of course, the same as a pencil sharpener. Insert the tip of the carrot into the hole and turn it around to peel it off.
It also comes with regular peeler teeth in case the carrot size doesn't fit in the hole (?).
By the way, "Karoto Peeler" is useful not only for peeling carrots, but also for peeling other vegetables into thin petals. The price is 9.99 pounds (about 1,700 yen), and the size is 5.5 width x 7.8 height x 4 cm depth. It is said that delivery to Japan is also being carried out.
