This cap was sold for several months at a price of 28-33 keys and in just one click the price was 18 keys, I agree, the effect is ordinary and uninteresting, but in combination with the cap it costs more than 20 keys, but not that not 18!

If you take other sites, then on the marketplace.tf price of 30 keys
