Across the listings the earrings are made from gold-plated metal, stainless steel, alloy, glass, resin, silicone, and zinc.
Sizes vary across listings. Examples given include small pendants and overall dimensions such as 0.39 × 0.70 × 0.19 inches (with ear hooks 0.74 × 0.70 inches), a 1.5‑inch length with a 0.39‑inch width, a jellyfish pendant listed at 12.5 × 6.5 × 6.5 cm (4.92 × 2.56 × 2.56 in), and some entries listing dimensions of 10 inches (L) by 5 inches (W). These show a range from small pendant sizes to larger listed pieces.
Activation methods vary by style. For the ‘ghost-in-a-bottle’ designs the listings say the glow appears after about 10 minutes of exposure to sunlight or violet light. Other styles (for example the jellyfish pendant) are described as emitting a warm glow at night, but the listings do not specify the exact activation method.
The listings show several closure types, including French wire (French hooks) and button-style closures. Many descriptions refer to dangle earring hooks made of stainless steel or alloy rather than post-back studs.
Some listings explicitly state that the earring hooks are lead-free and nickel-free, and at least one listing describes the hooks as hypoallergenic.
Designs shown in the listings include glass “ghost in a bottle” pendants and 3D jellyfish-style dangle pendants.
The listings indicate a count of “1 pairs,” meaning each listing includes one pair of earrings.
