Time Out says
If you’re to be stuck on an island with only one hyaku-en shop, you'd probably want it to be Seria. A combination of remarkably high product quality and premium store merchandising yields a palpable, 'This is a 100 yen shop?!' reaction. Seria’s fresh, friendly and homely feel makes it an all-round pleasurable experience to shop there. The product selection is roughly equal parts home necessities, DIY craft supplies, and clever knick-knacks. Seria stores are sometimes freestanding but also found inside most Marui malls.
