PentelQuick Click Mechanical Pencil, (0.7mm) Med Line, Canister, Assorted Colors (A/D/N/P/S/V), 36-PK (PD217PC36M)

Can you see the lead colour through the barrel?

Why does it cost so much more for the pentel quick click .7mm canister than the .5mm canister? I would Love to order them but i cant afford that much

what eraser refiills fit PD217P Mechanical pencil?

How many pencils included in a package? Description says 12 pencils, review says 1 pencil. So I am confused.
