Will my order arrive in one shipment? 

  • There are some products that may ship separately due to packaging differences and production time. 

    Do you ship internationally?

    •  Yes. Shipping rates are calculated at checkout. However, shipping isn’t available in some countries. Due to unsatisfactory delays, shipping to Mexico is not available at this time.
    • All orders for the STEM Epic Heroes card game are shipped via the United States Postal Service. While USPS lists 7-21 business days as their projected shipping window for international packages, we have found that some locations can take up to 30 business days or more.  
    •  International customers are responsible for any additional import or customs fees that may be imposed. Shipping fees charged on behalf of Mythic Lab do not cover any possible import or customs fees.

    • Orders for the STEM Epic Heroes card game, puzzles, and stickers are processed within 1-3 business days.

    • Please see our refund policy page for instructions on returning your order.



    Product Care 


    My t-shirt has a slight odor, will it go away? 

    • Yes, the odor is a completely normal byproduct of the printing process and it will go away once the shirt is washed.

    Printed apparel (direct-to-garment)

    • Printed apparel can be machine washed cold, inside-out on a gentle cycle with a mild detergent and like colors. Use non-chlorine bleach only when necessary.
    • DTG-printed apparel can be tumble-dried on a low cycle but hang dry works best. When it comes to ironing, use cool iron inside-out. Do not iron the print.


    • Our mugs are microwave and dishwasher safe.


    • To ensure that your posters last for a long time, don’t keep them in direct sunlight or outdoors. They can be gently dusted with a soft, dry cloth or a feather duster.
