These strap are almost identical to the Fitbit strap that came with my charge 3. They look similar but these straps have an extra loop to make them more secure. They seem to be made out of the same materials as the original Fitbit strap. The fit and feel on my wrist is just as good as the original and they attach to the charge 3 securely. The colors were just as expected in the picture of the product and I am very pleased with this purchase. Thank you for offering a quality product at an affordable price.
