Tyidzon Sliding Retractable Rubber Eraser, Soft Push Pull Large Erasers with Plastic Sleeve for Elementary Middle School Students Kids Office Supplies

these erasers are pretty good even though the packaging is entirely Chinese these erasers are high quality and if you run out of the eraser since the whole thing is a stick you can pull up the slider to give you more of the eraser and if you don't have the first eraser you can use the extra eraser to give you and replace it if you run out on both of the sticks I don't know where you can get more but what I do have to say is that these erasers erase pencil markings pretty good it's almost like it the pencil never even marked the page
