Martystuff and Sock Puppet City are now offering select merchandise through Print-on-demand third party vendors!  All of the stuff I'm sourcing I try to try out at least the base product, but please let me know if you're having any problems with it and I'll make sure to make it right! I also work to make sure that these factories are ethically sourced and certified.

From the nice manufacturer:
