The Peg To Differ 2.0 Pegboard Set is a significant upgrade from the original Peg To Differ Pegboard base set.In addition to improved aesthetics, the functionality and placement of the pegboards was improved. There are now specific slots for items based on their size which makes placing add-ons a breeze.The set is color-coordinated to match with the Do It Yourshelf 2.0 Cubbies and the Tiny Living SP allowing you to build a cohesive look! As a results of the improvements, some of the original Peg To Differ items are not compatible with the 2.0 version. Anything that is no longer compatible with the new Peg To Differ 2.0 pegboards has been included in this set - everything else remains compatible
