Tawawa on Monday No.509: The Wall of 103 cm
I thought "1,030,000 µm" would be better with the "10,000" in it, but I decided to keep it as simple as possible.
The title is a pun on the "Wall of 1.03 Million Yen" phenomenon, written in Japanese as 103万円の壁. Himura entertained using "103万㎛" instead of "103cm" in the title since it's just the same measurement value (1 cm = 10,000 µm) and preserves the 万 kanji (lit. "10,000").
