Where to buy

Our partner does not list this exact product yet. The search below looks for it on their site; the price there is theirs, not ours.

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 30 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.

Evidence

Recorded specification

Every value carries the source it was read from. A property with no recorded source is marked as such rather than presented as a fact. If one of them is wrong, tell us: it is the fastest way it gets fixed.
