I love the look of this Organizational system but I must admit the glass jar has me a little worried. They would be great on carpeted floor cause if they tipped over I think they would be okay. I would actually like a system like this at home for our Toy room which is getting overwhelmed with stuff. I recently made my daughter her own Stationary Vase out of a tall heavy glass vase I picked up in Target for $2. She keeps all her special erasers and pens in there in her own room. Mason jar Classroom Organization. Would glass work for you?
