It’s Sigma’s 10th Birthday soon! Everyone is invited!

This time we will choose 10 lucky winners! Each winner will get one Sigma pack for free!
If you already have all the activations, no problem – *take money!

Just follow a few easy steps:

1. Write how long you have been working with Sigma (1 year? 3 years? Or maybe 10 years?), and name one advantage of Sigma.
2. Make a photo of you showing “thumbs-up” to any Sigma product you own. We would love to see your photos!
3. Like and share this post as a public post on your Facebook page.

Don’t forget to attach the photo and your answers in the comments below.

The winners will be chosen on the actual Sigma’s birthday, February 2nd, 2022.

Ready. Steady. Go!
