Personal company stamps

Here you see two examples of personalised tabstamps,one with the name of a company.The other are children with a puppet, no idea if this is also from a company.
You also can order this stamps here. When you buy 1.000 pcs the costs are just the valueprice. You don't see much of these stamps on your own mail, but I know they out there. Better not soak this kind of stamps because then you have a tab and a stamp thats two but not the way you like it.
