Giotto Stoppino nesting tables

Giotto Stoppino table. Set of six nesting tables by Giotto Stoppino 1970, two sets of three nesting tables, so six tables in red plastic. The tables have small marks but nothing that takes away from their value and charm. The tables are original but I don't know why the previous owner sanded the description underneath all the tables but we can see on one. (see all the photos please). I'm always here for questions. Thank you
