KOKUYO Mechanical Pencil Sharp Black 0.5 White 0.5 Both of these have been used to a certain extent, so they have scratches and dirt. The KOKUYO logo on the black one is slightly faded. The white one was bought at a 100-yen shop. I think the barrel is a little thicker. Pentel Tough 0.7 TUFE This has only been used for about a week, but it is a used item, so please purchase with the understanding that it has scratches and dirt. I will take measures against water damage, but I will not use cushioning materials because it will increase the thickness.
