Chosen with you in mind
Most mystery boxes are completely random. Ours is different.
After you order, we’ll ask whether you prefer clothing or footwear, along with your size, style and colour preferences.
Where available, we may also consider your previous Olyndra purchases to help us understand the styles and fits you already enjoy.
You won’t know exactly what is coming until you open the box. That is part of the surprise.. but the selection itself will be thoughtful rather than random.
What you’ll receive
One hand-picked piece from our current Black Friday 2026 collection, which may include:
- Jackets and sweaters
- Dresses and lightweight knits
- Pants and other bottoms
- Shoes, trainers or other footwear
- PLUS NEW: Free BF 26 Mystery Gift now also included!
Every item will have a minimum value of £53 and up to £85.
