It's small and you can't do much strength on the watch case. The delivery time was very long, they insist on using Cainiao
I received the parcel in 19 days. The seller sent immediately. The tool performs its functions. Silumin material, varnished. Black steel screws only. If the silumin does not crumble, then it will last for my life. The description should be corrected. Because of this, 4 stars.
