luminous pen - Luminous is a rethinking of the gift pen. The inscription is placed on a removable piece of precious material on the inside of the pen. This allows the recipient to carry the pen without the inscription getting scratched or damaged, and to change the pen when wanted, or needed. The inscribed piece can also be taken out and left home so that it is not lost. The inscribed piece of material can be seen when taking the tip out and when pulling the two ends apart.
