Acrylic yarn with antibacterial and odor-resistant functions, with a charming variety of colors. Purchased in January of this year. I have a cat, so please refrain from purchasing if you have allergies. When shipping, I will pay close attention to hygiene and inspect for dust, etc., with adhesive tape before packing, but please understand that this is a personal inspection, so I would appreciate it if you could understand and agree. Thank you for viewing.
