Welcome aboard, Howard! Glad to hear your first aging was a success – that means you are hooked now! :laugh:
The paper clip trick was invented by C~W over a year ago and involves bending open a pc into a triangular shape. You then insert one of the round corners near or in the tip of the Sinbo sealer and it serves to keep the bag open enough to draw the air down. The clip should be sterilized before each use as it stays in the bag after sealing.
