Calling all ASTRO fans! This is a cool piece of Kpop merch – a titanium steel ring featuring MJ from ASTRO. It's made from healthy 316L titanium steel, which is anti-rust, water-resistant, and hypoallergenic for most people. The ring itself has a sleek design, often with a crystal detail. Here's the thing: it comes in ONE size only – a US size 8. If it fits your finger, awesome! If not, no problem, because they include a FREE black leather-like chain with lobster clamps. You can easily turn the ring into a pendant necklace, which is actually a really popular trend. It arrives in a nice silver or gold organza pouch, making it ready for gifting. It's a thoughtful and affordable gift for any MJ or ASTRO fan for a birthday, holiday, or just to show your fandom. They also have rings for the other ASTRO members if you want to collect them all! Just remember the one-size ring, but the free chain gives you a perfect backup option.
