The shapes are based on Dutch roof lines. Anyone who has been to the Netherlands, Amsterdam in particular, will have seen the amazing shapes.
The shapes come in both the Block (solid wood back, not see through) and the Window (see through block).
4 plain wooden blocks are included to help build the city.
The blocks work well together even though they are of different heights.
The sizes are based on 10cm x 2.5cm, fitting with our Bitcoins, our Lucite products and also with Bauspiel.
Please note: small marks on the gems are considered normal, it doesn't happen that much but occasionally there may be some small specks or a small mark.
Please consider this a sign of the hand work involved in making these blocks, it does not detract form the play value.
A cracked gem is definitely considered faulty, in the unlikely event you get one of those, please let us know.
