I don't categorize by cap value. Ain't nobody got time for that. See something you like, please contact me. I will actually reply to your neomail.
I generally go by Owls values, but I also take into consideration the ratio of people offering vs people seeking.
I am in the process of moving my wearables to my gallery, so my DTI list may not be as up-to-date. I encourage potential trade partners to also view my gallery (NP items are there as well): https://www.neopets.com/gallery/index.phtml?gu=return_of_itsy
99 = Items I like and/or regularly use for customizations. I am attached/semi-attached to these items and will ONLY trade other wearables for them
66 = Item is on a side account that may or may not have gift boxes
Wishlist items marked with 999 are what I am most after. The rest I am seeking casually.
Handhelds, wings, antlers, filters, effects, and other items that don't neatly fit into the other categories
