Where do you ship?

We currently only ship to terrestrial addresses.  At this time we are not able to ship to Russia or any other country that ends up on the USPS international services disruption list. If you do place an order to a country that is, or ends up on, that list we will likely have to cancel your order. Antarctica is iffy, though we have had some mixed success in the past.

What are the shipping times and options?

We ship via various carriers. Most orders to the US will arrive within 3-5 business days.  International orders should take around 2 weeks. Generally orders should be in the mail by the end of the next business day after the order is placed.

Are there any taxes or tariffs?

Package shipped outside the US may be subject to local tariffs and taxes.

What paper do we print posters on?

100# Silk Text

What is the t-shirts do you print on?

Unisex shirts are Gildan Hammer 6oz 100% ringspun cotton, except for the grey ones which are a 90% cotton 10% polyester blend. Women's shirts are printed on Bella+Canvas 4.2 oz 100% Airlume combed and ring-spun cotton.

Where are your products made?

Our shirts are printed in the US on Gildan or Bella+Canvas blanks, posters are printed in the US, and stickers are printed in the US or Europe.
