Just google 'Reynolds Handi-Vac', I think it's even on Amazon.com. If you're worried about mess, I would just wrap your shisha in some saran wrap (like Nahkla does) and then just vacuum seal that inside the bag. That way, the mess is only on the saran wrap. I just leave the tobacco in the open packaging and toss that in the bag. The quart size bags are plenty for 250g, that is actually what I have in the picture above, 250g of Nahkla sweet sweet and delicious melon.
