Everything sold on Stricken Designs is used by Stricken regularly. I stand behind every product here — I either designed it myself, or used it for a long time to make sure it does what it should and is thoroughly enjoyable.

All orders are dispatched next working day from our UK stock, in plain, unbranded packaging — nothing on the outside indicates what’s inside or where it’s from.

We ship worldwide. If something isn’t right with your order, get in touch via our contact page and we’ll sort it out — see our full Refund Policy for details.
