Upon opening and using these 12 inch bars I quickly realized that this was not the product I ordered. First, they were cut from a longer bar with raw, sawn ends. None of the ends have been beveled as per the Revain product description. Also, instead of being 12 inches long, they are 1/4 to 3/8 inches shorter. The only part of the product description that they matched was their diameter, 1/2 inch. Also, they were dirty and worn, as if they had been in storage for countless years. In another order I received two 48" long lab rods which matched the product description and also came with the Talboys tags. The 12" rods had no Talboys tags. The 12" rods were clearly cheap imitations.
