Napper's Mini:

Most sales are either untraceable or with dupes, but managed to find these 2 pure sales.

Sale 1:

Sale2:

https://backpack.tf/profiles/76561198042803042#!/compare/1563148800/1563321600

60 pure?

Wont take this as there is currently a clean seller quite a bit below this, seems like a very high outlier.

Total = 48

Sale 3:

https://backpack.tf/profiles/76561198100753690#!/compare/1568073600/1568160000

This sale wont be usable due to the spells.

Overall:

Sales at 78 & 88
