Gakken's Science magazine is no longer sold, but I purchased a bulk of them before sales stopped. I believe this magazine is in good condition, with no writing, tears, or cut-outs. All supplements are unused, but since they are unopened, there is no guarantee of the quality of the contents, and the equipment needs to be assembled by the user, so there is no guarantee of operation. Please understand this before making a purchase.
