TENMA is a brand of Farnell. I have never seen something original under the TENMA brand, only rebranded products.
Sometimes it is funny when you find the same item twice in the Farnell shop, under the original brand, and under then TENMA brand. I have no idea why they do that, or why they at all think they must rebrand some things under their own brand. Maybe a brainfart of some MBA.
