These are even better if you're a teacher who has a glutton of older #2 wooden pencils. They erase well enough without smearing lead marks. No smudge marks after use.

The sturdiness is what i like most. These are on par with expectations. Came in on time. Nice colors. Comes with bic mechanical pencils.

These fit snugly on regular pencils and offer rip-free usage on paper surfaces. They go perfectly with mechanical pencils whose erasers usually don't outlast the replaceable lead.

These are so flimsy they break apart when you try to erase. The whole top of the eraser shreds off of the part that attaches to the pencil after 2-3 eraser attempts. They erase ok, but are terrible quality.

These erasers erase better & cleaner. They erase everything so perfectly. Saves the pencils that have had their erasers used up.

These are racers are almost unusable! The whole inside is too shallow for it to stay on the pencil and the long eraser is so weak it flexes around. The cap is too small and it splits down the side as i try to use it as an eraser.
