BrickRelics creates detailed building block kits inspired by history, architecture, literature, art, and dark botanical themes. Guided by a stated appreciation for craftsmanship and the past, the brand presents each build as a way to engage with a story or iconic subject. Its collection includes gothic houses and collector sets, such as the Salem Witch House and Apothecary and the Black Veil Funeral House, alongside literary designs inspired by Edgar Allan Poe and The Legend of Sleepy Hollow.

Other offerings include creature and pet sculptures, mechanical display models, skull-themed creations, and botanical kits such as the Skeleton Sunflower. The products are designed for building and display, with many presented as collector sets. BrickRelics also shares previews of upcoming models and highlights selected best sellers through its online shop.

Customers can browse collections, purchase kits, and sign up for email updates about early product releases, special discounts, and member-only kits. The site promotes free shipping when customers buy two items and provides information on payment, shipping, returns, and refunds
