Pet Smart Door - Used, Excellent Condition

Received in January 2026 from Amazon and used for about 2 weeks.
Selling because it's no longer needed after purchase, but I think it's a convenient pet door.
* Disinfected with alcohol
* Operation confirmed

The tag attached to the collar was removed once and then reattached for listing, so there are small scratches on the collar hardware.
You can remove it again and reattach it to your own collar to use.

Includes:
- Original box (with scratches, etc.)
- 1 Smart Door
- 2 Collars with tags
- Included: 4 long screws (unused)
              5 screw caps (unused)
- Separately purchased: 4 short stainless steel screws
- Instruction manual (English)
All of the above are included. Requires 4 AA batteries (sold separately).
- Bonus: Test alkaline AA batteries used for about 2 weeks (please let us know if you don't need them)

?? The included short screws were also present, but only 3 were found. We are including 4 separately purchased screws of the same dimensions (the screw head part is slightly different).
* If you wish, we can also include the original 3 short screws (unused).
?? Upon closer inspection, there are fine scuff marks on the door part (there were quite a few from the beginning).
* Will be shipped via Mercari delivery in the original box.

This is a door that unlocks and allows passage only when a cat wearing the tag approaches.
There are 4 modes that can be selected from the buttons on the pet door. The large door allows even larger cats to pass through.
Outer frame: Approx. 30cm x 26cm
Entrance/Exit: Approx. 19cm x 20.5cm

We will only respond to initial defects. There are no noticeable scratches, but this is subjective. We would like to sell this to someone who understands that it is a used item. Please refrain from purchasing if you are sensitive. Please forgive any minor oversights.
