Hi Pat!
Glad you like this.
Blu Tack by Bostik....is a bit stiffer and can be manipulated to "pointier" shapes than any of the other poster putty I can get here in the States. Although I incorporate ALL of the poster puttys and erasers that are know to man....I've never been able to purchase BluTack here....so I order it from Mike Sibley, a well known UK animal artist who offers it online. I ordered some the other week...it arrived in 5 days from my purchase. Great guy..... check it out -
