Fruit?

Rounded?

You are so mysterious, fruit-like.

Founded near Boromeous Hospital at Dago, Bandung.

I was usually walking through from campus and accidentally mesmerized with the bluish addictive color.

Spontaneously, picked up one by one on the pedestrian side.

Not focusing on another, Trying hard to collect them and happily looked at for times.

Captured and took the best angle to show it.

Sadly, they were wrinkled so far and not aesthetic anymore.

Like you expect, threw them away while photos hold memories.

So, what do you think they are?

Next clue: part of tree.

Let me know in the comment yeah.
