Could someone tell me how much these old stens and lighter is worth?

I have 2 clay stens made by Gerz and 1 clay lighter made by colibri, All say they are made in W. Germany, and the stens have german writeing on them with the metal lid that you open with ur thumb, and the lighter is all clay with a metal top that you push down to spark. They all look brand new, no joke, brand new! I dont know how old they are but from what I tell you how much do you think they are worth, and if you can give me more info please do|||I'm sorry, but this is not the proper forum for an appraisal of items.You should try to use Google to find an appraiser in your area.
