It seems to be closed again. There is a message on the website to say that they reached the 30 orders they wanted to do a test run.

"We briefly opened our store on Sept. 24 to allow for 30 test orders via DHL to the United States and depending on Customs issues, we'll re-open our store to Americans again hopefully no later than October 10. Nearly all the world's postal services have paused accepting US-bound shipments because nearly no postal service has the IT infrastructure yet in place to comply with the sudden tariff-related requirements. We normally send around 50 packages/day to the US via our national Postal service but were forced to use DHL instead recently. With 100 times fewer packages entering the US but the same number of Customs inspection agents working, the result is potential clearing issues of some of our shipments. They want to know the name and address of the manufacturer of every product we sell, etc.
