Unfortunately I cannot add these at this time.  It doesn't look like it was a card released in USA, I'm not sure if they are licensed, and they are not part of a trading card game.

Search filters preferences should be saved on the website as long as you don't clear cookies between visits.

Example:

Generic search for Mario Party, returns 100 + items.

https://www.pricecharting.com/search-products?type=prices&q=mario+party

Filtered to games only and NTSC only.  Shows 48 items.

https://www.pricecharting.com/search-products?type=prices&q=mario+party&sort=popularity&broad-category=video-games&console-uid=&exclude-variants=false®ion-name=ntsc&show-images=true

If I do the generic search again for "mario party' I still see only 48 items.  The filters are still in place.

Please let me know if you see different behavior.

Are you referring to cards like this:

Or something else?  Please send me a list of these or a photo example and I will look into it.

They are probably all in the Promo and Japanese Promo sets rather than their own specific set.

Does this refer to this type of Naruto cards:
