Thank you for viewing.
Please be sure to read the profile before purchasing.

I remember buying this about 15 or 20 years ago when it was featured in a magazine (Men's Non-no?) as a limited edition item in two colors, gold and silver.
However, I bought a DS out of a whim and didn't really use it, and I bought a case for a DS I didn't use, so my memory is vague. I don't remember if it was really limited edition, where I bought it, or which magazine it was in.

I vaguely remember that it was a gold and silver color scheme and that I bought it after seeing it in a magazine.

When I tried to confirm the details for the listing, I contacted Yoshida Kaban's customer service to ask for more information, but they said they didn't have any records.
I couldn't find anything on the internet either, so it might be a very rare item.

I would appreciate any information from PORTER enthusiasts who know more details, apart from those who are interested in buying.

I'd like to check the market price and see people's reactions before deciding on the price, so I'll start with a high price.
Of course, you can buy it if you are satisfied with the condition!

It looks beautiful at first glance, but there are some areas where the surface is slightly peeled off due to friction depending on the angle.
