White/seafoam seaglass pens

These seaglass pens are a tale of two halves, the top half has a tube filled with seaglass while the bottom half is where the ink cartridge is.  

The pen writes in black ink 

To turn the pen on you twist the lower section. 

Please note that the pen colour itself is random but you choose the colour seaglass inside. 

I also send these tracked 48 royal mail (price reflects this)
