Europe Editor This week, as Brexit took effect, a company in Cork that sells sports posters to Europe and around the world ceased all direct online sales to the UK. "There's no point having the hassle," said Wayne Mullins, a graphic designer who runs Kobe Designs. "I'll just not send to the UK. I'll keep selling to the [United] States and the rest of the world." The UK market accounts for 50% of Mullins's sales. "It's a significant part of the business, but it's just not worth taking the risk for now," he said. Within days of a zero tariff, zero quota free trade post-Brexit agreement being struck, it appears that unforeseen, unheralded or just poorly understood frictions have come to the surface, hitting companies like Kobe Designs.
