An ita bag is built around visual storytelling—arranging enamel badges, acrylic standees, and small plushies behind a clear vinyl window. Adding an interactive, head-turning plush robot like Yukai Engineering's Mirumi outside the bag creates a striking contrast between your static display insert and a moving companion on your strap.
Disclosure & scope: Published by mirumirobot.com (retailer of Mirumi Pink, Ivory, and Gray). Specifications below reference Yukai Engineering's official US FAQ and reference measurements (checked October 2026).
1. Inside the Clear Window vs. Outside on the 10–15 mm Strap
Should Mirumi go inside the clear vinyl pocket or wrap around the exterior handle? Looking at the manufacturer's documented mechanics makes the answer clear:
| Placement Option | Why It Works or Fails | Recommendation |
|---|---|---|
| Wrapped around a 10–15 mm exterior tote or shoulder strap | Allows full head-turning clearance, exposes the head touch sensor for petting, and lets the microphone detect ambient sounds (US FAQ) | Recommended: Uses the wrap-around arms as designed (~10–15 mm strap diameter). |
| Zipped inside a tight clear PVC window | A 110 mm deep body (US Gray spec) presses against flat vinyl, blocking head rotation and muting touch interaction | Avoid while powered on: Never trap a motorized head mechanism against tight PVC sheets. |
2. Keep Sharp Pin Clutches & Ball Chains Away From the Fur
Because Mirumi's custom Japanese fur cover is non-removable and not washable (US FAQ), attach exterior acrylic keychains and metal ball chains to the opposite side of your ita bag so sharp edges do not catch on the plush pile. Match your color theme with Mirumi Robot Pink, Mirumi Robot Ivory, or Mirumi Robot Gray.
