HYQO4" Black Sew On Hook and Loop - 12"of Hook 12" of Loop Per Package.

What exactly are the dimensions? The description says 4". Also says 12" hook, 12"loop. But dimensions say 4.5 x 4.5 x 0.8?

Do you think fabric glue would hold the loop side to a nylon backpack? If yes, fabric glue recommendations?

I need a roll of the 4" hook and loop velcro. How may i purchase a roll of this? As small as a 30" roll would be great! thank you.

How many pounds can this hold?
