Thank you for looking! This is a stylish bracelet with a UV checker. The white bead section, sandwiched between silver and sparkling elements, changes to a deep pink color when exposed to ultraviolet light. You can tell the intensity of the UV rays by the color's depth. Originally, I myself am very sensitive to UV rays. I searched for an item that could visualize UV and be worn constantly, and I came across this bracelet. I find it useful all year round now. The surrounding beads are pink and clear aurora colors, giving a gentle impression and making it easy to match with clothes. It's also moderately glamorous. There are small silver ornaments as accents. Size: Free (elasticity in the clear rubber inside) Inner diameter: Approximately 6cm Inner circumference: Approximately 14.5cm I've taken photos with an unprocessed camera to make the condition of the product and the color change as clear as possible. I took photos indoors with the curtains drawn and in sunlight. I also tried taking pictures with various backgrounds, so please take a look. I handle it with care, but it's a home-stored item. If you understand, please consider it! Also good for using points (*ˊ˘ˋ*) #UV #Whitening #Sunscreen #Parasol #BeautifulSkin #Accessories #Functional #OneOfAKind #Summer #UltravioletRays #UVProtection #Photosensitivity #Cat'sEye Color: Silver, Pink, Matte Clear, Aurora Clear
