What was the present that Shouko gave to Ishida? What did Shouko say after that? What was the gift that Shouko gave to Ishida? Based on the manga, it’s for decorating plants, but what exactly is it called?

Could it be a marker for flowerbeds or something? Is it something entirely unknown except to the author?

N.B : Does anyone know what did shouko said in panel 2 ?
Putting my whole answer in spoiler as their purpose is explained in chapter 61.


   Those are indeed flower pot decorations. They don't have any specific name, they're usually called plant pot sticks, flower pot sticks, simply pot sticks or something along these lines depending on the website.
