About This
- Specifically Designed Refractometer For Saltwater Aquarium --- The algorithm is made specifically for testing seawater and saltwater. This is different from a standard refractometer which is not calibrated to check salinity of aquarium water and will give an error in your readings.
- Automatic Temperature Calibration --- The calibration process should be carried out with both the room and the instrument at 68° F. The refractive index of a liquid changes with temperature. Due to the automatic temperature calibration, any changes in ambient temperature from 50° F- 86° F will not affect the accuracy of the reading.
- Easy And Clear Reading For Saltwater Aquariums And Reef Tanks --- The refractometer comes with a focus adjustment on the eyepiece, this will give you clarity of the optics and a sharp line for easy reading.
- Comes In A Solid Case Includes Pipette And Calibration Tool --- This refractometer is not only built extremely well, but it comes with a durable hard case for easy storage of the refractometer when not in use. It also includes a calibration tool and a pipette.

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.

Great plated and nice designs to chose from . These are good and strong.
Size: 10 in-140 count
Love these plates for every soy. I normally use paper plates for lunch but I started using them for non messy dinners. We have even used them for spaghetti. They handled the sauce and meaball and sausage with no problem. I would normally U.S. China plates for something like the, I got lazy one night and used these I was pleasantly shocked they worked with no leak through.
