A golden thin metal lotus bookmark with black string.

In The Contemplation Sutra:

"These five hundred manifested Buddhas, at the same time reach out with their hands, praising by saying, 'Dharma son! You now are pure, having given rise to the unsurpassable aspiration for the path [to Buddhahood], I have come to welcome you!' When seeing this matter, they immediately personally see their bodies sit upon the golden lotus flower. Seated already, the flower closes, following the World-Honoured One from behind, immediately attaining rebirth within the ponds of seven treasures."
