Dear beloved costumers,

due to the new EU regulation PPWR we’re forced to step back from selling to most European countries (except Swiss and UK by now) from August 12th on.

We’re sorry but as a very small business we’re unable to pay for keeping it up

Orders from Germany and countries outside Europe stay untouched by this regulation.

We hope that each country will find a solution for small businesses fast so we can process your orders again.

From 25. August 2025 no shipments to the USA.

There will be no shipping from 08 Juliy to 13 July.

Choose a brand first, then pick the series/model you need parts for.
