This appears to be for school use, but the details are unknown. It looks unused, but it's difficult to confirm if all the parts are present. Please check the photos to assess the condition and consider purchasing only if you are satisfied. We aim to ship within 3 days, but there may be delays due to circumstances. If you need it urgently, please contact us before purchasing to confirm. Regarding the price, we do not accept price negotiations. We also do not offer exclusive listings, and sales are on a first-come, first-served basis. We will ignore requests for these. Instead, please use the "Offer Price" feature, and we will temporarily adjust the price only if the offer meets our conditions.
