These vacuum bags are strong enough to pressure your glue up but also sensitive enough to get around all of your curves. These are tubing – one end will be sealed and all you will need to do at the other is to add your hose and then tie it up with a piece of string or rope. These are wide enough to do a 32 inch paddle board. They are sold by the metre. If your board is 6 ft to 7ft or 1800mm to 2100mm – then you need to order 3m.
