Ok, so my post about the Zebra DelGuard was a duplicate (but I’ll leave it up anyway). So this Uni Kuru Toga is also pretty cool and you should buy it. Get it now for $9.

Not gonna lie, this seems like a pretty cool mechanical pencil. You can buy the Zebra DelGuard pencil with refill lead here for $7.
