What you are viewing are the remnant of my first Gunpla (Gundam model kit) that I got for myself in early 1990s.
I rediscovered these in one of my slash box along with some of my trading cards. I remember these were some spare set of a SD Gundam model kit. The main kit was discarded due to being brittle after years of direct sunlight, countless time falling from the height of my study table and the amount of stubborn dusts and stains.
Here's a hint of my first Gunpla. Can you guess what model it was?
