Bouwsteenwinkel. shop is a Dutch retailer specializing in LEGO® parts and related products, sold individually from its own stock in Bussum. Its inventory includes thousands of pieces across many colors and categories, from bricks, tiles, plates, doors, windows, wheels and Technic components to specialist parts and DUPLO elements.

Customers can also shop for complete minifigures, individual figure parts, complete sets, instruction booklets and accessories such as keychains and games. The website helps shoppers find items by part number, name, color or set number, and offers a photo-recognition tool for identifying unfamiliar pieces. Customers can create and save search lists, check which parts are available for a set, and track orders.

Orders are picked and packed from the Bussum inventory, with multiple products combined into one parcel. The store also offers used sets, which it says are reassembled from sorted stock and checked for completeness before sale. Bouwsteenwinkel.
