Won't these look great sitting on a window sill with the light shining through through? The blue or green glass fades into clear white and will integrate with a seaside decor.

The bottles are a generous 29cm tall and while you can certainly use them as serving bottles the practical side of me says "Put a tall candle in the top and make a feature out of it". 
 
The blue version is now sold out, but I'm reordering it and when it's in I'll update this post.  A limited quantity of the green version is still available.

This is a Gainsborough Giftware creation.
