the separation shelf is a shelf designed for couples that live together // it is built of a 2.5 meter oak lumber with grooves every 10 centimeters / and four metal supporters // in regular mode the supporters are inserted into the groves, and serves both as hangers as well as book supports that divides the shelf into different areas // when the couple separates, the supporters are used as working tools which can break the shelf into two parts / each partner takes his/her share (that is not necessarily equal) of the common property / a share that bears the break signs //
