Can someone recommend an inexpensive… cordless eraser with easy to find refills? Jet Pens who is my source for all things pen, pencil and paper has the Sakura Sumogrip?

A classmate made and sold these to classmates when we studied sketching.
He bought a bunch of those coffee foamers and just stuck any MP eraser cap on them. Sold them for less than 10$.
