Thank you for viewing. I hope this product will be helpful for those with a stoma (ostomy), artificial anus, or artificial bladder. [Manufacturer] Alcare [Product Name] Cellcare 1 TDs 30 [Specifications] Hole size 15mm, Stoma effective diameter 14-29mm [Bag Size] Length 300mm x Width 150mm [Product Number] 20151 [Retail Price] ¥4,850 [Expiration Date] May 2030 [Quantity] 1 box (5 pieces) [Condition] New, unused This is a clip-less type, making it easy to operate and reducing discomfort when worn. It prevents odors and stool leakage and employs a "ventilation recovery filter" that restores function if clogged. Even if gas escape becomes poor, squeezing the filter about 3 times will push the clogged waste back into the bag, restoring ventilation and preventing the stoma bag from swelling or leaking odors. *Due to shipping costs, only the product will be shipped via Takkyubin Compact or Nekopos. Thank you for your understanding.
