Sondey Biscuit Duo's chocolate

Sondey Biscuit Duo's are chocolate-flavored sandwich biscuits primarily sold through the German discount supermarket chain Lidl. Sondey is a private label brand used by Lidl for its bakery and biscuit products.

Because Sondey is a store brand, the manufacturing locations can vary, but production is typically based in Europe—often in Germany or neighboring countries like France or the Netherlands—to supply its vast network of stores.

The brand is owned by the Schwarz Group, one of the largest retail groups in the world. As a private label, Sondey products are designed to offer competitive alternatives to international snacks, maintaining high distribution efficiency through Lidl's global supply chain.
