I received this as a souvenir from Silicon Valley a long time ago. I didn't use it much because the writing feel didn't suit me. It's old, so I don't think the eraser will work. I'd guess the lead hardness is somewhere between HB and H? Please understand that these are unused but old. I will send them in an old box. Set of 8 black pencils with the Apple logo. - Quantity: 8 - Color: Black - Design: With Apple logo - Lead Color: Black Thank you for looking.
