Overall, this is a great frame, with one caveat. The instructions tell you to use a white crayon to make the linking numbers on the frame easier to read, which is great advice, but I used a chalky white artists crayon, which did faintly scratch the plastic. This is my fault though, not Broken Token's. The scratches are imperceptible except upon close inspection, so it's really not a big deal, but I would use a soft, waxy Crayola crayon if I could do it over.

Functionally, the pieces fit together easily, and have just enough give that placing the tiles in the allotted space is snug without being difficult. They have a little give, but in a good way. They also fit very nicely in the allotted storage space that comes in the Imperious Twilight organizer for the base game.

These fulfill their intended function well. They adapt well to different player counts. They store easily with the rest of the BT inserts.

A great addition to keep your board tiles in place. Honestly I don't know why something like this (maybe not as nice) are not a part of any game that requires you to assemble smaller pieces together to create the play board.

These frames are great addition for keeping your board organized. They fit well and are especially helpful during the setup phase.

This is a neat piece of kit that solves the issues of not having a boarder from the get-go.
Fit and finish is so and so but after a bit of work it goes together right quick, and after some more work with some crayons the text is also becomes legible.

Although I feel as though I am the only one that have noticed that there is a fault with one of the pieces, namely the A-B strait piece.
It points the wrong way for a 4 player game, and it can even be seen in the first promotional photo, where the Winnu honesystem is not where the 4P arrow points.

This is a source to much personal annoyance, though other than that it does it's job and that is the most important thing.
