Thank you for viewing. This item is knitted with 100% acrylic yarn using Toray's antibacterial and odor-resistant fibers. It's cherry pink. Diameter: Approximately 9.5cm (excluding the loop) Set of 4, with loops. I try my best to knit carefully, but this is a handmade item by an amateur. There may be distortions, looseness, and fraying. Each piece has a different texture and size. There may be yarn end treatments and knots from when the yarn was purchased. The colors may differ slightly from the images. Please understand and acknowledge these points before purchasing.
