Traded for Voltaic Hat Protector Universal Translator (Painted The Bitter Taste of Defeat and Lime)

12 to 16 keys -1 key (Taking into account the key that was included in the trade) = 11 to 15 keys

(Not taking the paint from the Universal Translator into account here.)

Note that most Voltaic Universal translators are going for about 13 keys, which is almost the middle of the 12 to 16 keys range, which is why I didn't bother putting 13 as the range isn't just 13.
