Merch

There is a sparkk shirt. There is no shop.

Volunteers wear it while they teach, and the only way to get one today is to email and ask for one.

Email about merch

Or write to sparkk.digital87@gmail.com yourself.

We are a nonprofit, not a store.
There is no checkout on this site and nothing here is sold. Money that reaches sparkk goes to running free classes at public libraries.
Asking is the whole process.
Write to us and say what you are after. We will reply with what we actually have rather than a catalogue of what we do not.
There may be a wait.
We are teenagers running classes, so we cannot promise a date. If we cannot help you, we will tell you that instead of leaving you waiting.
