Work emergency

I brought these to test the FE of a waste water treatment plant. I needed them quickly as our usual suppliers were out of stock of the ones we use normally. These are a little difficult to work with but the product itself is OK a little cheap feeling but saved our bacon for a few days.

Great Product

I use these for making soap. This helps me filter and purify the oils I make so I can have a better product to turn oils into soap. Will definitely keep buying
