Thank you for viewing! (^-^) Natural stone: Pink Tourmaline Silica Bead size: Approximately 6mm Hook: Surgical stainless steel Discounts available for multiple purchases! This is a handmade item. I make every effort to create it carefully, but it does not compare to mass-produced items. I hope you will handle it gently. As it is a natural stone, there may be cracks or inclusions. I have several cats. Please refrain from purchasing if you are concerned. ・I am studying to polish natural minerals such as Larimar. My polishing skills are still developing, but thank you for your understanding (*´ー｀*) Please read my profile if you have a moment☆彡
