Review: Very impressed with the quality! - I bought 6 sets of these in different lengths and am highly impressed. Sturdy, precisely formed, cleanly cut, individually wrapped in protective plastic, then boxed. They all arrived in excellent condition, no dings, dents or bends. There were a few minor burrs on the ends from the cutoff saw, but they were so minor 1 or 2 strokes of a fine file removed them. Honestly, if I didn't have a file I could have left them as is--VERY nice!
Review: Zero scratch surfaces - Kudos for shipping them with full individual plastic wrap and cushioned tube packaging. Great product, impeccable finish.

I recently purchased 10pcs 48inch T Slot 2020 Aluminum Extrusion European Standard Anodized Linear Rail, and I was able to get an open box set for a great price. The value for this product is excellent, especially if you are collecting extrusions for a build one day. The aluminum extrusions are well-made and durable, with a smooth and consistent anodized finish. They are also very versatile, as they can be used for a variety of projects and applications, from building furniture to creating custom 3D printers. Despite being open box, the extrusions I received were in excellent condition, and they were packaged securely to prevent any damage during shipping. Overall, I would highly recommend 10pcs 48inch T Slot 2020 Aluminum Extrusion European Standard Anodized Linear Rail to anyone looking for a high-quality and versatile building material. The value is excellent, especially if you can find an open box set for a discount.
