Monkey Blocks by Bornelund
Monkey blocks are fascinating blocks that maintain balance in unusual positions due to hidden weights inside. Simply stacking them will cause them to collapse, so you need to consider the location of the hidden weights while stacking. The included idea book presents 34 different stacking methods, but once you understand the presence and location of the weights in each of the three colors, you can sample stacking methods not found in the idea book. This is a game that fosters the ability to think for yourself through trial and error.The main body is complete, but the box and instructions are partially torn.Please consider purchasing this item with the understanding that it has been previously owned.Please refrain from purchasing if you are overly sensitive.This item is stored and inspected by an amateur, so please understand that there may be oversights.If you have any concerns, please feel no-cost to ask in the comments beforehand.
