This Counterweight Lanyard Attachment is used to balance the extra weight added to your lanyard off of your neck. The weight of a typical bag is roughly 2oz. Fabric is a 65% Poly and 35% Cotton Blend. Weights are enclosed in a thick plastic bag inside of the counterweight pouch and sewn shut. Bags are available with Velcro that can be wrapped around the Lanyard or a sewn loop that you slide the open end of the lanyard through. If you would like a different type of fabric, fabric color, or weight for your bag, please send me a direct message and I will work with you to create an item that is exactly what you need. *Lanyard is not included*
