Wise Elk ceramic building kits are designed for construction enthusiasts from 5 to 99 years old. Imagine your child can build a house, a lighthouse or even a castle by hand. Small plaster stones and ceramic tiles are tightly matched with safe non-toxic glue. Sets are simple and natural. So no adult help is needed. Wise Elk Plaster Construction Kits develop fine motor skills, accuracy and logic and are perfect for school projects. All construction sets are reusable. To deconstruct the building, put it in water for a few minutes, dry the bricks and use PVA glue to build it over and over again.
