Kseniia Nel has created such a fascinating painting on one of our fountain pens. These must be the magical moonlight feathers from some fantastical creature! Under normal light the feathers look wonderful. Against a teal background, the feathers are outlined in silver, with occasional dots of silver, sparkles of gold, and a subtle shimmer that changes along the length of the pen. Then, under ultra violet light the design becomes something completely different! Certain elements stand out, others recede. (Ksseniia has used a UV reactive ink that makes the design a secret that only the owner will know about … and she has provided a tiny ultra violet torch that we will ship with the pen, to enable you to see the hidden design.)
