This Aqua glue marker by Prym is a glue stick for securing pieces of fabric, braids, lace and zip fasteners before you sew them. This glue stick is super useful to have in your sewing basket! The glue has a yellow color when applied so that you can easily spot it, but after drying this color disappears. The glue is completely washable and leaves no traces whatsoever. The marker can be refilled with appropriate refill cartridges for the Aqua glue marker.
