Some sort of thin sanding tape needed, for between fingers..

Hello! Does anyone know of any kind of thin sanding tape that could be used between fingers? My Sakaki has nasty uneven areas between his fingers, which I'm surprised at. I would have thought these dolls would be very carefully finished, but there's a lot of digs and bumps and general uneveness around the fingers. Annoying, really, and I know it's going to bother me if I don't fix it. Or maybe I should try living with it for awhile... Anyway, it would still be useful to know if there is such a sanding material... Thanks for any help!

 

Hi Fitz! Thank you - that's exactly what I need! Great! Thanks again!
