The heart is filled with cotton. Length: Approximately 50cm (excluding the string) Instant purchase is welcome. This is a handmade item made by a beginner. I make them carefully, but there may be some slight imperfections such as歪み (distortion) or fraying. I understand there may be some shortcomings, but I would appreciate it if you would consider this with understanding. Thank you very much ( ˶˙ᵕ˙˶ )
