Look what I have.These are the 1993 BIC Wavelength Body Heat Pens. These pen were made in the USA and will change color as your hand warms up. I opened a pack and they still work. They all have black ink so you could replace the refill with BIC Cristal For Her, BIC Cristal Bold or the BIC Shimmers. Any of these will do and are all in your local store. I will be giving away one package of BIC Body Heat Wavelengths. Leave a comment by 16 Dec. 2012 and maybe one of these packages of BIC pens will be yours. US only on this one. I may add something else to the package. No telling what can be found down in the supply room.
