Is it worth buying in Japan?
MUJI's official Taiwan site does not carry this barcode; the Taiwan-side price is a seller listing on momo Shopping. Many such sellers ship cross-border directly from Japan, so shipping and delivery time are separate and this is not the authorized Taiwan retailer's shelf price.
- With a 1.5% foreign card fee: Japan comes to about US$0.80, still below the US by US$1.60.
- Break-even rate 0.0200 USD/JPY: above it the the US sticker is the cheaper one (this check used 0.0066, cross-converted from the Bank of Taiwan yen and dollar rates).
Before you buy
- Verify Japan JAN 4550002794132 against the spec (さらさら描けるゲルインキボールペン ノック式; item no. 02794132)
- The Taiwan side is the momo shopping site, not MUJI Taiwan's official channel; the page does not state whether tax is included.
- Shipping cost and delivery time for cross-border direct-ship sellers are calculated separately; go by the page's listed price and stock on the day of purchase.
