I just bought my water brush and keep asking myself why I didn't do it sooner; so much easier than a water pot and paint brush. Well worth the cost!
Wilton Water Brush Reviews
Pros: Very easy to use
I love these brushes, they are very easy to use and easy to fill with water. I have one filled with water and one with vodka, which i use to stick numbers and letters on cakes. I always manage to tip small pots of water or vodka. With these there is no mess and you do not have to keep replacing the lid as you use it, so it is always on hand ready to use. Also their is always the right amount of water on the tip so the fondant does not get to wet. I have not tried these with glue made with gum trag or anything but as long as the glue is not thick, i don't think there would be a problem. I would highly recommend these.
