Where can I find the last “eye” to open the red box?

Question

I just discovery the Old game " Crimson Room. and it's not very hard. but the "clicks" are hard to do As @wipqozn said in the CHAT

IT got a lot of hyper about being difficult, but the hitboxes are very, very small, so it's just about clicking every possible pixel until you open something.

This is how I'm atm.

I believe that is somewhere in this part. It's the only area that I didn't found anything.

I found the items in those locations:

• CD case (left top drawer)
• Memo (right top drawer)
• Ring (at the bowl near the stereo)
• Cassette tape (below the hack)
• Battery (behind the bed)
• Silver key (window)
• Golden key (below the pillow)
• Metal stick (behind the pillow)
• Power supply cable (left bottom drawer)
• Small box (right bottom drawer)
• Key (inside the stereo)

Answer 1

You need to click near the bottom of the curtain in order for the ring to fall out.
