One thing I find as a 6 foot 6 male is that a lot of items were not made with people like me in mind. This even extends to products like fidgets.
Thankfully, I have been able to find at least one brand of fidget that does have several size options and that would be the Tangle family of products.
In my opinion, the Tangle Palm Classic(click to use my affiliate link) size of product is actually the best one, as it fits in my hands and takes both of them to play with it.
There are also pocket sizes and more, but I’d say those are more for being on the go than at home.
I will try to keep everyone updated as I find more products in this category!
