Thank you for viewing. ※ Brand new, unopened. I used to put this under the cat litter, but one day my cat suddenly started to dislike it and pulled it out, so all the stock I had stored became useless. ※ Please refrain from purchasing if you are nervous about home storage by a private individual. It's a shame that I can't offer it at a lower price because of the considerable shipping cost, but I would appreciate your understanding before purchasing. ※ No individual sales.
