This is a tiny little breadboard... half the size of a half-size breadboard! 

As of Sep 8, 2022 - This Tiny breadboard has been updated to make plugging and un-plugging boards and headers a buttery-smooth operation. Updated design also includes a metal plate. The metal plate is used to stick the breadboard on for mechanical support, and to keep the paper on the bottom from coming loose and sticking to things. secondly it provides a small amount of shielding to your circuits, and if you connect an alligator clip from it to earth/ground you will get an earthed shielding as well.

Measures 1.8" x 1.4" (46mm x 36mm)
Perfect for tiny projects and for sticking onto the top of Arduino protoshields!
