Level requirement for meso bags?

Well, I was going to start fresh in Yellonde and planned on buying the Gold Meso sack so I could level without constantly worrying about my mesos. However, even though I am level 10 I am unable to purchase them, yet I can gift them and buy everything else in Cash Shop. Any help? To be more specific the Buy and Reserve buttons are unable to be pressed i.e grayed out.

I'm pretty sure you need to be 15+ or 16+ to buy certain things from the cash shop. I couldn't buy a store permit on my mule until I was 15 or 16, so train until there and try it out.
