So what does Nexon expect me to do?

Okay, from the Hyper event I have:

- Hyper Honeybee Suit
- Hyper Honeybee Wings
- Hyper Honeybee Antennae Hairband

I don't want these items anymore. They're clogging up my inventory. The main problem is:

- I can't put them in CS (specific flag on them says they can't be moved to CS storage)
- I can't drop them (Cash shop items can't be dropped)
- I can't sell them (Cash shop items can't be sold)
- I can't trade them for stamps (do not apply)

So what am I supposed to do with these things? How do I get rid of them? They're wasting space in my already packed Eqp tab.

EDIT: Oops. Should have posted in Maple Q&A. Sorry.
