[ Meka receives a text message notification on her phone via the app:

Please come to the laboratory to retrieve your special gift!

When she arrives, she'll find a small box, wrapped in her own and HSS's colors, inside of which is a shiny, metallic film.

Although there is no explanation on how to use the item included with the gift itself, if she checks her Pokedex she'll find instructions there for what to do with it. Alas, she does not have a Pokemon to use it on... this time. ]
