R > npc to get rid of bound items

[Lelouch---]

I'd like to know if there is a script shop or something like that to sell or discard bound and rental items only. 
Or a way to make them sellable.

D:\rathena\conf\battle\items.conf

 

// Allow selling of bound/sell restricted items as Itemshop currency? (Note 3)
// 0x0 = Bound/sell restricted items are unable to be sold to Itemshops/Shops
// 0x1 = Bound items are able to be sold to Itemshops
// 0x2 = Sell restricted items are able to be sold to Itemshops
// 0x4 = Bound items are able to be sold to Shops,
//       because most of trade restricted items are still able to be sold to Shops
// 0x8 = Only Guild Leader can sell BOUND_GUILD items to Shops or Itemshops (if 0x1 or 0x4 set)
