OMRON SB-182 / 1 box Periodontal Care ・Shipped via regular mail (no compensation). ・Change to Mercari mail (with compensation) for an additional 100 yen. Please contact me before bidding. ・There is no envelope that fits this product, so I am using a handmade envelope using flyers, etc. ・In the case of a new package, the box is 2.5cm thick, so it will exceed 3cm if protected with bubble wrap. Therefore, the box will be placed directly into the envelope. ※ We do not respond to price negotiations.
