Famicom console, initial model with square buttons, with 5 Famicom cartridges

This is a set of a valuable, early-model Family Computer (Famicom) console with square rubber buttons and 5 game cartridges.
Neither the console nor the cartridges come with boxes or manuals.
Everything included is shown in the photos.

The console shows signs of aging, with dirt and scratches. In particular, there are traces of sun discoloration and yellowing, despite surface cleaning before listing. Please refer to the photos for the condition.
The rubber buttons on the controllers feel firmly attached.
(Rubber buttons tend to detach with use.)

Regarding functionality, I haven't been able to confirm it because I don't have a TV or monitor to connect it to. However, I have confirmed that it powers on (you can see the red light of Zippy Race in the 4th and 5th photos turning on and off).

The included adapter has poor contact at the base. The power cuts out due to the poor contact, so it might be better to replace the adapter.
The RF switch is a used item purchased from a flea market that was confirmed to be working. I haven't used it since I couldn't get a TV.

The cartridges have all been tested and confirmed to work on a compatible console.
However, since it's a compatible console, I cannot guarantee perfect functionality. Please consider this as a reference.
The cartridges have a lot of dirt and small scratches. Also, although I couldn't photograph it, they have names written on them with a permanent marker, which is common for used items.

This is a set sale of the console and cartridges, and I'm not considering selling them separately. Please purchase them as a set.

This is a valuable item because it's an early model with firmly attached rubber buttons, but it also has some issues.
Please consider the above explanations before making a purchase.
