The heat sinks come in seperate bags, each bag has 3pcs of different sizes, all feature a square shape. They have 3M double side tape and are well finished. The smaller weights 0.6g, the bigger 1.7g and they are about 8.9x8.9mm and 14x14mm, respectively. Their thickness is about 6mm. Great heatsinks for passive cooling. Highly recommend them for hobby electronic, modifications and replacements. Their build material and finish is excellent.
