Okay, don't expect significant differences with a similar keychain that simply won't have the Nike logo. It is a simple keychain that I believe will meet everyone's expectations. The strap is not elastic and is quite durable. After 5 months of use, there are no loose threads. I constantly have it with me and I like to twist it around my hand like a fidget spinner. It has fallen several times, been wet, and overall has endured some rough handling. Despite this mistreatment, the plastic parts, the keychain, and the strap look brand new. It hasn't gotten dirty at all, and generally it doesn't get dirty easily, but I bought the black color. Maybe the white one requires a little more attention. The size is expected and satisfactory, with the edge located in the center between the diaphragm and the waist, although this may vary depending on body type. It's very positive that the keychain is detachable from the strap. Pleasant and beautiful. The price may be a bit steep, especially with shipping, but it's our well-known Nike, so I didn't expect anything less. I see no reason not to give it 5 stars. I hope I covered everything for you!
