Thank you for viewing from among many items. This is a handmade accessory, a resin accessory that encases natural stones in resin. The stones are aquamarine and crystal. I've added a large amount of aurora hologram and included aquamarine and crystal. It's a gorgeous piece. Necklace chain Size: Approximately 42 + 5cm If you have any requests for wrapping, keychains, leather cords, or changes to the chain length, I will accommodate them free of charge, so please comment (o^^o) If there are no comments, it will be as is. Also, if you wish to purchase multiple items, I will discount the shipping cost by 200 yen m(_ _)m Because it is a handmade item, there may be some slight distortions or air bubbles. The color may appear different depending on the angle of the photo. The strength and quality of the chain, etc., are not as high as commercially available products, but thank you for your understanding. No. 399
