No operational problems. I will discount 50 yen if you purchase with other products. This is a used item and will be sold at a bargain price, so please understand. If you purchase multiple items and only the software (without the case), I will discount a total of 100 yen. Please contact me in the comment section if you have any questions. Depending on the product, there may be no instructions or accessories. To prevent substitution, there is no guarantee for any reason. The condition of the products is subjective, so please understand it as a reference. If there is a problem such as an address error due to an input error by the buyer, or if there are any other deficiencies, we will charge you for the re-shipping costs, etc. Even if the product is listed, it may not appear in the search results, so you may be able to find the product you are looking for by viewing it from the profile section. Thank you for your cooperation.
