This is a bundle of two 204-0022-01 adapter PCB strips and the 920-0031-01 solderless breadboard.
Each PCB is a strip of two DFN-to-DIP adapters with a twist. These have the patented Schmartboard|ez technology to make soldering surface-mount devices easy. Your SMT part will sit in grooves that hold it in place and already have solder in them. So all you need to do is put a chip in the grooves, apply flux, and use a small enough soldering tip.
The adapters ship as two PCBs that can be snapped apart easily, creating four individual boards each of which supports a 10-pin DFN chip with 0.5mm pitch (3×3mm body).
Two strips of 40 male pin headers are included. These strips also can be snapped apart so that you can create the individual segments needed when these boards have been separated.
The Bred Blox solderless breadboard has 830 tie points (126 five-point terminals plus four horizontal bus lines of 50 test points each for easy connections to common lines). The board has interlocking features so that you can connect multiple Bred Blox together to make a larger prototyping area.
