@Vespur hi there! No worries because this is a fairly recent change, but I'm no longer doing more than 20 unique types of item per person per day. (That's two PMs worth of item slots, and seemed like a reasonable place to cap daily wear and tear on my wrists.) You've requested 28 different kinds of item if I counted correctly. I'm still happy to send you 20 different kinds of item up to the pre-existing category limits, if you'd like to revise your requests? If not, I will send the first 20 things you requested in an hour or two.
Edit: additionally, I do not have leather strips in stock. Please be sure to check that your requested items are on the inventory sheet before requesting. ^^
