Glue Fast moisteners are simple, effective, and inexpensive. They apply water using wick rollers to transfer the water. This is much more effective than the "brush-type" moisteners which actually scrape adhesive off the back of the label. They do the job quickly, cleanly, and economically. This moistener is used for wetting envelopes and labels.
The Model C can moisten labels up to 4.5" wide, and up to 5.75" wide for the Model S, by guiding the flap under the bar.
