Our B828 blocks are the same size as our B882 blocks, but they are magnetized through one of the 1/2" dimensions. They attract each other end-to-end as shown in the bottom picture. They are great fun to play with and can be very useful as fridge magnets because they are easy to grab to move. They can be used with our B882 blocks to make some interesting sculptures.
