Shipping paintings is easy but expensive. Since I use ArtMove for all my shippments I feel safe that my paintings will arrive in the best condition and as fast as possible.  
Shippment cost varies from country to country, but from 2000SEK up to 5000 SEK is normal. I've decided that all my paintings will be shipped worldwide for 2000 SEK fixed prize, no matter where in the world a painting will be shipped. Within Sweden shipping cost 1000SEK fixed price.
Free shipping in Stockholm.
If you for some reason want to return your product you will have to pay the shipping yourself. You always have 2 weeks.
Don't hesitate to contact me if you have any questions!
All the best, Sabina
