Modena Paste, Padico, Modeling Paste

Modena Paste - Padico Modeling Paste (Less than 250g)

I purchased this for use in sweets deco.
Used a few times, then stored long-term (over 5 years) with the inner and outer lids closed.
The condition is gooey.
It says 250g, but I estimate about a quarter has been used. The weight including the container is 276g.

Would anyone who can use it be interested?
It would be best if you know how to use it.

Thank you for looking.
