Ddalgi Store is a fan-focused K-pop shop offering official merchandise and original fanmade products for collectors and enthusiasts. Its range includes albums, lightsticks, photocards, album inclusions, plushies and other official goods, alongside accessories for displaying, protecting and carrying collections, such as binders, sleeves, toploaders, cardholders and bags. The store also stocks collectibles and blind-box items, including Baby Three plush toys, and products inspired by groups such as Stray Kids and artists across the K-pop scene.

Ddalgi designs and makes its own merchandise, including printed paper goods, posters, stickers, acrylic keychains and pins, apparel, tote bags, charms, jewelry and personalized drinkware. Some items are handmade in Colombia, including felt character plushies and selected accessories; its original designs are made for fans and may be identified as fanmade rather than official merchandise. Customers can also explore preorders, special orders, Japan Box offerings, and workshops and events. With a mix of official goods and distinctive, locally made creations, Ddalgi aims to help fans collect, personalize and express their fandom.
