I bought this thinking it was a mechanical pencil, but it's actually a knock-type pencil, so I have extras. The lead is about HB in darkness. The lead length is only as long as in the second image. I've been using it by replacing the lead with compatible ballpoint pen refills. ※ See image 3, the replacement refill I found compared to the original pencil lead. I think there are other compatible refills as well. The design is very cute, so I recommend using it as a ballpoint pen! Any two for 500 yen! I will ask you in the comments after purchase and then ship!
