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 shape is a Window Shape (see through)
The blocks work well together with the others in this series, 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.
