Following the July 2026 re-introduction of the Diddl mouse to the German-speaking market, the brand's resurgence has triggered significant price inflation on secondary marketplaces. While products remain available at standard retail prices in supermarkets and drugstores, resellers on platforms like eBay are listing items at heavily marked-up rates. Specific reports indicate sellers asking as much as 820 euros for nine notebooks and approximately 154 euros for a single scented A6 notepad, despite a retail price of roughly 5.99 euros.

In response to this trend, Alexander Strehlau, a spokesperson for the drugstore chain dm, stated that resale via third-party platforms is ‘outside the company’s sphere of influence’. He expressed regret regarding the high prices and emphasized that the company aims to keep products available to customers at fair prices through its own stores.

Looking ahead, the brand's expansion continues with confirmed plans to return to the Polish market in early 2027. Distributed by Kukartka, a company under Passion Cards, the upcoming Polish range is expected to include stationery, gadgets, and gifts featuring the iconic character to appeal to both nostalgic fans and a new generation of consumers.
