    DID YOU KNOW? Ever since men began to carry pretty stones around as amulets or for personal adornment, they have longed for a way to keep the wet sheen that seemed so attractive. If you are interested in the history of rock tumbling, you would need to go back to about 4,500 BC. Research tells us that it was probably the Chinese who found a way to use water and sand to polish rocks. The process could take years. The Chinese are also thought to have been the inventors of the very ingredient that makes modern rock tumbling practical — silicon carbide abrasive. Ordinary sand wears out. Individual grains lose their sharpness and cutting edges or eventually pulverize into powder. None of the ancient stone carving or polishing techniques can be considered a form of tumbling, though. Ancient civilizations lacked the constant and uniform mechanical power source that makes modern tumbling practical. Primitive techniques do have one important thing in common with modern tumbling, however, and that is the goal of both is to retain as much as possible of the precious material, keeping the natural contours of the original stone.

    Sleek, Durable Laptop Sleeve That Punches Above Its Price
    Size: 13.3 inch, Color: Red
    Right out of the box the sleeve felt premium—sleek exterior, soft interior lining, smooth zipper—and it’s held up flawlessly through daily use with no pilling or wear. My 13‑inch MacBook slides in snugly without adding bulk, and the padding gave me real confidence after I accidentally knocked the bag off a chair and the laptop came out unscathed. The front pocket fits my charger, hub, and other small accessories neatly, making it practical for coffee‑shop days, though I do wish it had a grab handle, but it is ok. For the price, this sleeve delivers excellent protection and finish that rivals much more expensive options.

    Triple Check Your Measurements. No Margin For Error.
    Size: 15 inch, Color: Space Gray
    Exterior is exactly 15" wide making for a snug fit of my 14 1/8" laptop. This snug fit was what I was looking for. Any tighter and it wouldn't fit at all. The material is of good quality and the lining is soft. The padding is minimal but should be adequate for everyday use. First impressions are this is a very good quality sleeve. Time will tell.

    13.3-inch bag is too big for a 13-inch Surface Pro 11
    Size: 13.3 inch, Color: Gray
    The bag is very good, but I am returning the 13.3-inch size bag, as it is too big for a Microsoft Surface Pro 11 (13-inch screen). I should have done a bit more digging through the description to realize the size. It would have been better if the pictures showed actual inner dimensions. I have just ordered a 12.3-inch bag. The smaller bag should be adequate. EDIT: The 12.3 inch bag came in. This bag is perfect for Surface Pro. Great fit! The front pocket holds the power brick and a small mouse, and a bit more space for flash drive or similar.

    Nice color and good quality
    Size: 14 inch, Color: Navy Blue, Size: 14 inch, Color: Navy Blue
    I had originally bought this for my work laptop (MacBook) and it fit perfectly. But now I use it for my personal which is a 13.3in MacBook Air. I like the feeling of the case. I have a crack on my screen and I feel like this case offers more cushion than my previous one. I wouldn’t say this would save my laptop from a fall but I feel more confident as it’s in my bag that it’s getting enough protection. I also like the color and it’s spacious enough to hold a laptop charger, note pad, pens, etc.

    This glass protector was the easiest one i have ever used. went in on easily and only a couple of bubbles that were easy to push out. It seems to be made with quality material and fits perfectly. Got the first one right so now i have a spare.
