Fingeroll is a concept for a lint roller that uses less material, and takes up less space, both for shipping and for the end user. The handle is done away with, swapped out for a hollow core. A washable, reusable silicon roller (rather than wasteful adhesive) rotates around the core.

I don't know that I've ever experienced pain when using a lint roller, but perhaps the assignment was meant to target people with wrist issues. I think using one of these might be a little janky, but I'd try one out; I like that it uses less material, takes up less space and can be reused. As an owner of dogs that always seem to be shedding, I can attest to how wasteful the standard type of lint roller is.
