Diagrammatic Pieces define the pieces moves on the item itself. This removes the need to memorize the moveset to the symbol needed in many forms of chess
Western Chess - Maple Landmark
Wooden Pieces with the moves written on the bottom (so you have to lift them up to see)

Japanese Chess - Dobutsu Shogi (in the greenwood)

Cute animals with the moves indicated by dots around the edge of the piece, probably the best diagrammatic set I've seen

Japanese Chess - Kumon Study Shogi set
Very similiar to dobutsu shogi, but with the original character written in the middle instead of a cute animal. The wood feels good in the hand

Eastern chess sets will often have "westernized" pieces, that are different non-language characters symbols, but still require people to memorize a symbol lookup table.
I'd love to find diagrammatic options for Chinese Chess (XongQi), but I haven't seen any - do you know of options?
Because the question takes a backseat to showcasing the OP's product link. They aren't trying to sell us on some carnivore product though (as seems to be their normal posting mode), so it was probably an accident. I guess once you start selling bullshit non-stop it's hard to stop sounding that way. The way they were so quick to pull and regurgitate those stats about you was a real internet marketer move though. Sneaky of you to trick them into exposing how creepy they are.
