/ case
Read our case with the Municipality of Lisse
The Municipality of Lisse called in Elfa Elementenfabriek when the public clock on Square came to a standstill due to a battery that was difficult to replace. Thanks to rapid analysis and specialist knowledge, Elfa supplied the right battery, so that the clock worked again within a short time. The municipality now has clear information for future management.
