DALIX high quality PVC slats are made of smooth vinyl. Do you have vertical blinds in your house sliding door or your window blinds? This is perfect for those pesky breakages when 1 or 2 slats are broken. Keep these at your house in case your dog or children accidentally run into them - breaking them at the top in the process. Feel safe that these replacement slats are of equal or greater quality than the ones that exist in your home. You can cut these to the height of what you need them if your vertical vanes are not the full 82.5 inches long. Just take a pair of scissors and snip away to the correct length from the bottom.
