I've started to sell stickers and the feedback is great apart from the fact they don't stay on that long and some come off really quickly. Would sticking some tape over it be OK to hold it in place? Will it affect the frequencies? Thanks
我已經開始賣貼紙了，除了貼紙貼的時間不太長，而且有些貼紙很容易脫落之外，反饋都很好。用膠帶黏上去固定可以嗎？會影響頻率嗎？謝謝
