They are the rolls we have in our home and use every day. Pretty standard if you ask me. Have you ever been to the market? Toilet paper comes in all shapes and sizes, "standard" is a pretty loose term.
You boys should relax and enjoy this for what it is. Simple fun.
We had a great time watching our 9yr old break the record yesterday and we are proud of him for taking the initiative, collecting the TP and urging us to post it. I wish you the best in your future attempts.
