3. 可因應需要選擇設計、自行調較大小
4. 列印時用AI (adobe illustrator) 程式開啟此PDF
    檔，便可調較貼紙大小，複製貼紙到新artboard

Remarks
1. Sticker dimension is designed to be 10x13 cm, 
    equivalent to that of the safety stickers on
    MTR train glass doors.
2. Remember to trim off the 4 rounded edges
    of the stickers if you desire a higher degree
    of imitation.  
3. You may select the designs and adjust sizings
    depending on your purpose for the stickers.
4. To print, open the PDF with AI (adobe
    illustrator) to adjust sticker size (if needed),
    copy the stickers to a new artboard and 
    arrange your printing layout, or pass it to the
    print shop and have them arrange for you.

- an A4 size canvas prints 4 10x13cm stickers
