This shop in Baarle-Nassau / Baarle-Hertog is partly in the Netherlands, partly in Belgium, the border splits the shop. Because of corona-restrictions border traffic has been limited and in Belgium all non-essential shops are closed. So in this shop only the product in the Dutch side of the shop can be purchased.
