UPDATE

Added 2 new versions:

• Stronger Heavy Duty Bag Clip - it has additional clip that you can add when everything is screwed together to make it hold better if the bag thicker.
• Longer Stronger Heavy Duty Bag Clip - it the same as the Stronger Heavy Duty Bag Clip but its 20cm long.
• Clip for Clip - it is only the clip that you can add if the bag is very thick, or if one breaks. (clip even works on regular Heavy Duty Bag Clip)

Info

Simple heavy duty clip made for bags like rice, coffee and anything else that you can think of. it has screw that you screw on the end and it holds great, because clips easily brake.

I have snack grabber on my profile too, its great for keeping your hands clean and doing stuff like reading or gaming.
