Our clothing dividers are made of a professional grade flexible plastic and NOT made of cardstock/paper. They are VERY durable and will not crack or break under normal use. We have never had a complaint noting damage of the closet divider as a problem. The divider holds a professionally printed label that is made to fit the common closet rod. They are sold, usually in sets of 5, but extra dividers can be added for a nominal fee. The wording on the Clothing Divider can be anything you wish. Examples are: 0 - 3 months, 3 - 6 months, 6 - 12 months, 12 - 18 months and 18 - 24 months. Another example is days of the week or you could put the name of the clothing item, Jeans, for instance. You could add to your set by adding "Newborn", "2 Toddler, etc". or you could add "Weekends" and as far as adding clothing items, you could have a set of 10 to 15 with all the choices available. Additional dividers are priced at $2.00 each and the cost of shipping will also increase with the addition of 2 or more clothing dividers added to your order.
