OMRON SB-182/2 boxes Periodontal Care ・Shipped via regular mail (no compensation). ・Change to Mercari mail (with compensation) for an additional 100 yen. Please contact me before bidding. ・As there are no envelopes that fit this product, I use a handmade envelope using flyers, etc. ・For new packages, the box thickness is 2.5cm, so it will exceed 3cm if protected with bubble wrap. Therefore, the box will be placed directly into the envelope. ※ I do not respond to price negotiations.
