2 IKEA IVAR storage systems. The original including only 5 shelves each, we added a total of 4 shelves for 15$ each shelf.
Condition like new, we bought them 2 years ago and we are selling them because we move out of the country.
Very flexible and sturdy storage system, made from untreated solid pine wood, no plastic, great quality!

Price new for one IVAR system: 155$+30$ of supplementary shelves = 185$
