This listing does not say which warehouse ships it. Most orders leave China, so expect import VAT and a carrier handling fee unless an EU warehouse is chosen at checkout.

No current price: our own estimate is 600 SEK. It is a rough street figure rather than a quote, and the retailer above confirms the real one.

Some links on this page earn us a commission at no extra cost to you, and that never affects any verdict on it. How this is funded.
