https://gladiator.tf/listings/604866b0046391bb48d69713 - buyout 125 keys

I assume the 130 keys match for some reason, but I also don't see why it'd sell for above its buyout in pure.

Untrace

I would think you need to confirm the "150 pure" sale you think you have.

As well as perhaps confirm the 130 key sale since I'm not too sure

Conclusion

150 won't fly here
