If they meet the size requirement, I think you can put them in your 311 bag.
I just wanted to let you know that, in coming back from Mexico into the US, the rules may be different. That government has its own version of TSA and some things that are permitted going from the US to Mexico are not permitted in reverse. I had bamboo knitting needles confiscated by Mexico on our way back last March. Be sure to be aware of what their requirements are when you come back.
