1.是否已在板上發表註冊文? 是 2.註冊文位置(文章篇數/精華區位置/AID碼): z-10-8-32-4-47 3.是否有標示在雙和範圍內之面交地? 有 4.是否已看過版規? 是淡金黃色，適合長時間戴著。目前看到最好的耳塞減噪約-34~33db, 較差的約-23db. 坊間常見的3M橘色耳塞約-29b,比較低，且戴久耳朵會痛。還剩15副，每副兩個15元，地點在四號公園或興南夜市附近，有意願訂的朋友請推文或寄信預定數量，賣完為止。:-D -- Sent from my Android -- ※ 發信站: 批踢踢實業坊(ptt.cc), 來自: 114.136.26.60 ※ 文章網址: http://www.ptt.cc/bbs/ShuangHe/M.1420521868.A.754.html
