I purchased 10 36" window boxes with these liners last summer. Great concept, however, I agree with another review they do not last very well at all. Replacing them again this year, sadly, it is very difficult to find another liner for these window boxes. May research purchasing a roll and making my own. Love the boxes as they stand on their own and that's what I needed.
Since the planters for which these liners were purchased are designed for the side planting technique, we do recommend the liners be replaced with every planting.
