What is Crystal Candy
Crystal candy is a handmade sweet with a crunchy crystal shell and a soft, chewy centre. Inspired by Japanese kohakutō, it’s made using agar agar, giving it its jewel‑like shine and unique texture.
Most crystal candy comes in simple cube, stick or shard shapes, but Treats With Rei uses custom moulds to create detailed designs — hearts, animals, desserts, characters and themed shapes.
Each piece is made in small batches, so colours, patterns and textures naturally vary, making every treat one‑of‑a‑kind.
