This is very ancient fossilised tree trunk made visible through a very contemporary digital microscope.
There are fossilised trees in Wales' hills, valleys and beaches.
And there are also beautiful trees - not least magnificent oaks - all across Carmarthenshire, and one favourite concentration of all that natural beauty is in Tregib Woods close to the banks of the Towy.
So, now you can sit down and have a quiet - and beautifully colourful - tea (or coffee) thinking of Wales and, particularly, walking in the woods of Wales.
This quality ceramic mug is a good size (8 x 9 cms), and printed from top to bottom.
It is printed in the UK specifically for you, and will be delivered to you within a week of you ordering, or to any other UK address you choose.
As designer mugs are often £20 to £25, we hope you agree this represents excellent value, especially important if you are tempted to buy a set of 4 or 6 identical or complementary mugs.
