Bit of a nube question but I have this

Will it be ok to keep the cigars in this box? It seems to have an ok seal, Ive taken 2 of them out to make room for a water pillow and Ive nicked my mini hygrometer from my secondary humidor which is reading a constant 67% rh, but its right next to the water pillow. There doesnt seem to be much empty space in the box so I was just wondering if you think the humidity will be constant throughout or not. 
 
My first purchase that came with a box, and its such a nice box I dont want to not use it. 
 
Thanks in advance for any help
