does anybody know these candlesticks  

China stuff?
I recently picked one too and the only informations I found are from this: http://www.light-your-home.com/aluminium-candle-holder/62.html
Maybe those (from the link) are only knockoffs from something more valuable? They sure look good anyway.

Ikea
With those stickers they are definitely Ikea. Available a few years back, maybe longer. I have no idea as to designer...
edited to add: I see these all the time in thrift stores....they usually still have Ikea stickers on the bottom as well.

Yep.
IKEA.

THANKS
Thank you
Emerone, Solange and Spanky for your input.
Wel you can not expect to win them all :-).
I'm just glad to see that other people appreciated this design as well even though it's Ikea stuf.
