Children often use pencils and colored pencils, and of course the number of pencil sharpeners increases. If you buy a handle-type or electric-type product, you will often get in the way as an adult and get rid of it.
The "PET bottle sharpener" sold at the 100-yen shop "Daiso" is a pencil sharpener that can be used by attaching it to an empty PET bottle. The "N700 Series Shinkansen" and "C11 Steam Locomotive" are designed so that you can enjoy it as an interior even when you are not using it.
The body has a built-in pencil sharpener, and the mouth of the PET bottle is attached to the round hole at the bottom. When you open the tip of the vehicle, insert a pencil, and rotate it, the shavings accumulate in the PET bottle.
The sharpened pencil is sharp to the tip, and there is no problem with the finish. It is very easy to carry and you can see the accumulated amount at a glance.
A slim type bottle is easy to tip over, so a small capacity bottle with a diameter of about 6 cm is recommended. Also, use a well-dried PET bottle so that you can dispose of the trash smoothly.
By the way, it seems that the yellow Shinkansen "Doctor Yellow" for inspection is also on sale, but unfortunately it was out of stock at the store I went to. If you see it, you may be "happy" just like the real thing.
The price is, of course, 108 yen.
