Kimberly-Clark has initiated a voluntary product recall on Cottonelle® Flushable Wipes sold by Costco due to the discovery of possible microbial activity on the wipes.
You can return the unused wipes and get a full refund. I returned the product yesterday and got full money ($16+tax) at my local warehouse.
Multiple lot impacted: BI012505X (example)
