I can't confirm if these items work because my DS is broken. Therefore, I'm selling them as a set of two junk items. Please consider purchasing if you are okay with this. *Please refrain from purchasing if you are prone to complaints or are overly sensitive. *Regarding price reductions, due to increased shipping costs, I am unable to offer discounts. Thank you for your understanding. *Even if we are in the process of discussing or negotiating, the item will be sold to the first person who purchases it. Thank you for your understanding. *I have a child with a severe physical disability at home. Due to the season, they are prone to illness and may require hospitalization. Therefore, shipping may take some time. Please consider this before purchasing. *I am raising six children, and shipping will only be done on weekdays. I am unable to ship on weekends and holidays. I will ship within 4-7 days from the following week. I will contact you if there are any delays. Thank you for your consideration.
