PC on Gold Cruel Oni Daggers of Dagger Mastery

Could someone please value these:

Gold Cruel Oni Daggers of Dagger Mastery

Piercing Damage 7-17 (requires 9 Dagger Mastery)
Damage +15% (while Health is above 50%)
Lengthens Deep Wound duration on foes by 33%
Dagger Mastery +1 (19% chance while using skills)

Many thanks.

I sold that EXACT pair of daggers just now; same mods and everything. My price check said 20k, so I'm assuming it's the same thing here.

Yup, 15-20kish should be the sellable range.
