I love the look of these mechanical pencils but have given up on this style because, for the life of me, I have not been able to figure out how to refill the lead once it runs out. I have taken these apart and tried inserting lead every which way, and it's just a huge hassle and I have not ever done it successfully. I think a mechanical pencil should be easily refillable and reusable, but these just end up in the landfills once the lead runs out. Not a good purchase.
