Flute with case and beginner's guide, Soleil

I started learning the flute on my own 5 years ago and purchased this item (see 9th photo) and practiced for about a year.

I took it out again recently and tried playing it, but the notes around F in the lower register (the key pressed by the right index finger) are difficult to produce and sound airy. Other mid and high notes played without issue.
Those who intend to use it seriously will need to adjust the keys.

·͜· ꕤ︎︎ For those who, like me when I started,
Want to try playing the flute but aren't sure if I'll stick with it,
those who want to practice fingerings for now,
or those who want to practice embouchure with the headjoint,

I would like to pass it on to someone who can ensure a smooth transaction (*^^*)
Please understand that this is a used item, and returns or holds are not accepted.

☆ There are marks where a lip protector was applied to prevent the lips from slipping. I purchased and used one separately. I have 2 remaining, which I will include.
☆ I also purchased a separate support to prevent the left fingers from slipping, and I will include that as well.

Due to the lighting of our home's downlights, some parts may appear somewhat orange, but it looks shiny and beautiful.
