JoyTiTi oil pastels 12 set, preparation of lightfasntess test

I bought this small set of oil pastels in Kairo in April 2024. It is the first time i try oilpastels, and I enjoy them. This set was very inexpensive, so I am curious if they are lightfast. I made swatches for the test on the 25th of March 2025. I will check back to this post after exposing the swatches to light for some months, and update the post with the results of the test.
