I have received the Power Blox Standard Set which contains 45 pieces in the box. This set allows you to lit up the your creations with a unique power block.
There are more Power Blox products available on their website. They also have another line called Circuit Blox which offers new possibilities and experiments to be made. You can purchase their products from their online store. Note that all prices are in US money.
