Daiichi Pan Decochara Seals (stickers) come with Pokémon Pan, a baked bread good sold in Japan. This sticker is from the 18th series, releasing back in 2000. Daiichi Pan even has an official archive of all the stickers that have ever released as part of the Daiichi Pan series, the list can be found here.
It’s a pretty basic and kinda boring sticker, nothing fancy. The text in the blue bubble (ハガネール) is Steelix’s Japanese name, Haganeil. Mine has some slight discoloration likely due to the age of the sticker.
While these don’t seem to be too expensive, they aren’t super common. There are only two listed on eBay at the time of writing this.
