They're very pretty looking (and cool at the .3mm spec) but at $10+ dollars and such tiny erasers, no thanks Jeff, LOL
Erasers are actually smaller than shown.
But who needs them when you have Pentel Hi-Polymer Block Erasers!!!!
To be fair though, I've taken architectural design for shits and giggles and my professor gave me a bundle (2 dozen) of those pencils for free..
