My customers swear by these.

We have been buying kling for years. We won’t ship a tree without including a kling card.
Wier Tree Farm

We have used kling as a giveaway for more than 20 years. We give each customer 4 sheets with the recommendation that they use one a week. People return year after year and want to be sure that we still have it. You know how people are when they get something for nothing!

....a sale is not complete without the kling card! Molly Gorman

Last spring I broke off a small fir tree and put it in apail of water with 2 Kling cards and 90% of the needles are still on the tree. Henry White (December 2011) Cross Lake Farms
