plastic bags for sand filling

[admin_exported]

I was considering buying a pair of Q Acoustics 1000st speaker stands but apparently they are not supplied with plastic bags and putting the sand directly in is not an option.
I guess it's not that easy to find bags that have the right size... Any idea?

the only thing i can think of would be some swingbin bin liners. not gonna be an ideal fit, but shouldn't take up to much room.
