I found two of them in:
- City Center, back shops (not in the main corridor), probably 2nd or 3rd floor, around I Spy Book Shop or Hobbies Shop
- Souk Al Falah, behind Fanar, just small shop taking basketball, football jersey orders or simple number embroidery. If I am not mistaken not far from small entrance after loading bay, if you're walking from Fanar toward Souk Asiry.
