Pure Crystal Filter 4 pcs for Dogs

This is for dogs.
I am selling this because I no longer need it.
It was unopened, but I opened it due to shipping costs.

???? Will be shipped via Yu-Packet Post.

?? I cannot respond to initial defects, etc.

???? I apologize, but please refrain from purchasing if you are concerned about minor details, if you do not communicate throughout the transaction, or if you plan to pay at a convenience store.
I apologize, but many people do not pay by the deadline when using convenience store payment.

For packaging, I may reuse clean materials if available (e.g., bubble wrap).
Please rest assured that I only use new OPP bags.

If you have any questions, please confirm them in the comments before purchasing.
