The RectorSeal Fortress 84105 Line Set Cover Kit is a premium HVAC line hide solution designed to protect and conceal exposed refrigerant lines, drain tubing, communication wiring, and electrical cables.

Strength in Numbers
Size: 12 Packs, Style: Lunch Napkin
I have perpetual allergies which cause me to sneeze and sneeze. Buying tissues at supermarket is so expensive, so I took a chance and bought these, and they are great! Soft, strong, and I'm saving a bundle by not spending $3 or more on a small box of Kleenex which lasts maybe 2 days. I recommend these for all-around use. You won't regret it.

Raised the price $10 ???
Size: 12 Packs, Style: Lunch Napkin
These napkins are great and I am a return customer BUT. I can’t believe all the sudden they raised the price $10. I am not happy at all. I will still buy them but I will use them much less Better for entertainment and my pocket. This is how I fight back when they raise the price.

Great quality
Size: 12 Packs, Style: Lunch Napkin
Napkins arrived quickly. There is a lot of them but we will use them. They are good quality, have not had any rip on us. They absorb liquids and food pretty well, cleans the hands like they should. They feel like normal napkins, soft but tough enough to wipe with. Good product that I will continue using.
