Our pens are easy to use, just pull off the cap, turn the nozzle clockwise and remove the small plug. Turn the nozzle back on counter clockwise and they are ready to use. Squeeze the tube with even pressure and you're ready to go! Our glitter glue pens may also be used as an adhesive. To adhere rhinestones, sequins or other decorations, please allow 30 minutes to dry. To unclog tips, insert a paper clip into the nozzle.
