Working with wood, a lathe, and a few chainsaws, I generate a "ton" of sawdust and shavings that fill up my Shop Vac far too quickly. The bag was REALLY full so I went to Lowe's to get a new bag but it wasn't there. I found VEVA online and ordered a pack of 10 'J' type sachets. They arrived quickly, good quality and less than $4 a bag. Now I can change my vacuum bags before they almost burst. I will now use VEVA for my vacuum bags.
