Are kilim rugs reversible?

Good day, I have a question regarding kilim rugs that I've been considering for my home decor. One aspect I'm curious about is whether or not these rugs are reversible. Could you please clarify if kilim rugs can be flipped over and used from both sides, or if they have a specific design or material that restricts their use to one side only? Your expertise in this area would be greatly appreciated. Thank you for your time and consideration.
