Product Details
Secret messages are fun to write and even more fun to decode with this invisible-ink pen set. A small ultraviolet black light in the pen caps illuminates notes written with the invisible ink (it can't be seen in regular light) and makes super kids supersleuths.
  • Includes two invisible-ink pens and erasers.
  • Import.
  • Online only.
  • This item is not intended for use by children under three years of age.
