MAFmini1.0 Pet Oxygen Concentrator + Oxygen Chamber S Set and IKOU Oxygen Monitor

Purchased on Yahoo in February 2025, but my beloved pet passed away before I could use it, and I won't be using it in the future, so I've decided to sell it.
The MAFmini1.0 Pet Oxygen Concentrator + Oxygen Chamber S Set and the IKOU Pet Oxygen Monitor were purchased separately.
After purchase, I opened them for inspection and only turned on the power. I believe they are in good storage condition, but please refrain from purchasing if you are sensitive.
All accessories are shown in the photos, and I have included everything from the original purchase.
Please note that I do not accept price negotiations, cancellations, or returns after purchase. I would appreciate it if only those who understand this would proceed with the transaction.
