tanning pen

this is a good tool for summer season!
it's a special pen that puts or removes a thin layer of sun protector over the skin.
depending of the pen you want to use (the Tanning-Pen or the Tan-Remover-Pen) you can chose the effect for your next "sun-tattoo" for the summer:
draw your own decoration as if your skin were a paper and then go to lay on the sun.
the sun over your skin will do the rest
