The picture shows two of the hex-ID washers. Only one is included. You only need one for the Savage slipper assembly though so it's ok. Speaking of the washer, it is absolutely essential that you use it. Otherwise your slipper will loosen itself and scatter your slipper parts all over the road and your friends will laugh at you.

What reviewers say

Three reviews, all rating the set 5/5. Two verified owners were satisfied. One reviewer noted that the product photo shows two hex-ID washers but only one is included, which they considered sufficient for a Savage slipper assembly. The same reviewer stressed that the washer must be fitted, as the slipper may otherwise loosen. A French-language reviewer praised fast shipping and expressed satisfaction. A Spanish-language reviewer valued the parts as hard to find in local shops and said they must be ordered online. The reviews are few and brief, so the picture of long-term performance is limited.
