242p: ??? Ensky - Pokemon Advanced Generation Bromide Gum 2 - Pocket Monsters Advanced Generations Bromides card (Starmie)
Your Starmie matches in style to this Wynaut card, which is found on this wrapper for AG Bromide Gum 2.
This website (エンスカイ ポケモンブロマイドガム２ グレープの感想・クチコミ・商品情報【もぐナビ】) lists the JAN code as 4970381036188. Theoretically, you could use this barcode to date the gum cards (by rainbow): Pokemon Poker Cards - #21 by rainbow
More recent Bromides Gum wrappers clearly show the manufacturer as Ensky.

Excellent Topsun Vs resource (by bbobrob): Topsun/Top Battle Versus/VS Card Resource
PSA lists these as 1998, although I don’t know of any sources other than PSA for dating these cards.

See above resource.
CGC lists these as 1997, but I am also unaware of any other sources for dating these cards.
