Does anyone know the dimensions of the inner shipping box used for the PYO unicorns?

Hopefully this is the right forum for this question haha because I am not asking about the PYO itself, just its box.

Okay, why? Well, in exactly 27 days I will be leaving Canada for the first time in my life (yeee!) to visit my best friend (meeting her for the first time!) in Texas. With the Canadian dollar so poor and with shipping being rather horrific, I’ve stayed away from this forum to avoid the temptation but since I am going to be in the states, I realized that I have a great opportunity here to dodge some significant shipping charges which usually make buying a larger PYO like the unicorn a huge ‘nope.’ (It’s about $50 to ship one to my part of Canada which definitely makes it prohibitive. Ouch!) However, I am still trying to figure out if this is possible, so because I would be bringing the windstone(s) home in my carry on (luggage I am bringing not,) I was hoping that there was somebody who might know the dimensions of the inner shipping box (as I plan to ditch the outer one which of course will be done at my own risk. I am sure that others have done this before though!)

Basically, I just want to see if the box would even fit in my carry on. 🙂 It’s a standard two wheeled rolly suitcase.

Anyway, thank you so much for your time! 😀
