I have an investment in the product (being married to the creator), but the All Rolled Up
game roll — along with a folding dice tray — means that I have pens, pencils, 100+ dice and counters, cards, and something to roll those dice in combined into a single easily carried and stored package.
I helped my wife with the original design because while a standard dice bag was fine for holding dice, it got more complicated if you added stationery or cards. A box is great, but it takes up a lot of space. The wide mouth of the dice bag part along with a flat bottom means that you can turn it into a sort of bowl — meaning that you have a thin layer of dice to dig through when you have a lot in there, so the digging isn't too messy. I have deep dice bags where it's like playing a Lucky Dip stand at a fayre.
The range also has a pile of generic and licenced designs, approved with the originating companies — like Free League, Chaosium, Pelgrane Press, Ulisses Spiele, Cubicle 7, and Games Workshop, as well as artists like Ralph Horsley (MTG, WFRP) and Russ Nicholson (Fighting Fantasy, AD&D).
I know that my wife has put her life and soul into creating these things, by hand, and taken the time to source the best materials and get agreement to use the most eye-catching images from major tabletop game properties. We have people who bought theirs 5 or 6 years ago coming to us to show they're still in use and working just fine — including when we attended Gen Con 50 a few years back.
