The Heart Key Treasure Box series from Yinhe Yuni channels the core Jirai Kei aesthetic — structured sweetness with an edge of drama. The JSK is built around a front lace-up corset bodice that cinches the waist and creates a defined silhouette, while the oversized bow at the chest — studded with pearl accents and a small ribbon center — serves as the focal statement piece. The plaid fabric runs throughout the JSK in a classic grid pattern, grounded by a tiered skirt with multiple ruffle layers and a sheer lace-trimmed hem that adds lightness and movement. Side ribbon ties at the shoulders allow for fit adjustment and add a playful detail. The included white puff-sleeve blouse provides a soft contrast to the structured JSK, with a lace-trimmed collar that peeks out at the neckline. The matching shorts underneath complete the set for a fully coordinated look. Available in Plaid, Black & White, and Pink & White — each colorway carries the same silhouette with a distinct mood.

Let customers speak for us
I was initially worried it might look cheap on... but omg, it’s stunning! The overall quality is great, it feels really high-end and textured. I couldn't tie it properly by myself so my waist looks a bit thick here, so you definitely want to get someone to help you lace up the ribbons to really cinch in that waistline. I’m wearing two petticoats with it—a thin pumpkin petticoat underneath and a black fluffy petticoat on top.
Honestly, this looks amazing. The material is very soft and doesn't scratch at all. Super comfortable to wear. Also, huge shoutout to the shop for the fast shipping. I was in a rush and messaged them, and they shipped it out the same day. Great product, great service.
The quality is amazing and it's so cute. Wearing it gives me such a 'tsundere ojou-sama' vibe.
So versatile even without the collar. The skirt is super full and has amazing poof. Pure perfection
Bon produit, la taille est tout à fait correcte et tombe très bien.
J'adore cette robe elle est magnifique, même si vous êtes petite et fine comme moi (1m52 41 kilos) la taille S ne sera pas trop grande ni trop longue 💜
Et même si vous avez très peu de forme les bretelles ne vous tombera pas sur les épaules ✨️
En plus il y a un laçage au dos un peu comme sur un corset, ce qui permet de resserrer la taille et c'est vachement pratique 💜
Le tissu est d'une qualité incroyable vraiment doux et brillant pailleté ✨️
Honnêtement elle vaut largement son prix je la recommande totalement 💜
このコルセット気に入りました。横に骨が入ってなくて、少し樽型ですが締め付けが強すぎず、私にはちょうど良かったです。
普段使いしてもご飯も食べられるので気に入って残しました。新調した白い姫袖とも相性抜群！あとファスナーが下へ引くタイプなのが本当に使いやすいです。大満足です！
