Binoculars with roof-like prisms in their optical construction provide compact design due to straight-line position of eyepieces and objective lenses. They are more expensive due to complex manufacturing and are providing many advantages for more demanding users. They are less sensitive to impacts and abrasions and are incredibly impervious for water and dust entering the construction. They are usually purged with nitrogen or argon gas, which also helps to eliminate internal glass fogging. Compared to Porro prism binoculars, they are more likely to withstand extreme weather conditions. Very good ergonomic design of this straight-line construction makes them less difficult to hold in hands and eases your portability immensely. But compared to Porro prism binoculars, this construction makes light transmission less permeable and thus providing darker and less sharp images.

I wanted this type of bottle and found it to be the best price, when others were charging double for a colored glass which I didn't want. It's more traditional and allows the oil to be seen. Thanks for having this product.

The jars are exactly what I need for a craft project. I ordered 30 bottles and 12 arrived as piles of glass in the bubble wrap they were wrapped in. I called customer service and they apologized and shipped me another 12 bottles to replace the broken ones.
