Best Hanaka Layout for a 20–30 Pin Collection

A collection of 20–30 pins is large enough to create a dramatic Hanaka display, but the best layout depends heavily on pin size. If all 20–30 pieces are standard 58 mm badges, they will not fit as a clean, non-overlapping single-layer grid on Hanaka’s approximately 34 × 21 cm insert. A clean 58 mm baseline is closer to 15 pieces.

That does not make Hanaka unsuitable for a 20–30 pin collection. It simply means you should treat the collection as a rotation pool or use mixed pin sizes instead of forcing every badge into the same display at once.

Layout 1: 12–15 hero pins, rotate the rest

Choose the strongest 12–15 pins for the current theme and keep the remaining pieces as a second rotation. This is often the best-looking option because every badge stays visible and the display can change without buying another bag.

Layout 2: centerpiece plus supporting pins

Put one special badge, photocard, or decorative holder in the center. Arrange smaller or standard pins around it in a loose frame. This works well when the collection has one favorite item you want people to notice first.

Layout 3: mixed-size constellation

If your 20–30 pins include many smaller enamel pins rather than only 58 mm badges, spread the largest pieces first and use small pins to fill controlled gaps. Keep enough space around each item that the artwork remains readable.

Layout 4: two visual zones

Split the wide window into left and right groups—for example, two characters, two costumes, or two color families. Give both zones a similar visual weight so one side does not feel crowded while the other looks empty.

Start with a paper mock-up

Mark a 34 × 21 cm rectangle on paper and place all 20–30 pins inside it. Then remove items one by one until the layout stops feeling cramped. The pins you remove become your rotation set. This is a useful way to let the physical collection—not a theoretical number—decide the final density.

Do not confuse “fits” with “looks good”

Overlapping can increase the number of visible pins, but it also hides edges, text, and character art. For oshikatsu displays, the goal is usually not maximum mathematical density. The goal is a composition where your favorite merchandise can actually be seen.

Use the removable insert to your advantage

Build the arrangement outside the bag, photograph it, and compare versions before fastening anything. See how to use the Hanaka removable mesh insert for the full workflow.

My preferred approach

For a 20–30 piece collection, I would display the strongest 12–15 standard-size badges at one time, or use more pieces only when many are smaller than 58 mm. Rotate the rest seasonally, by character, by costume, or by event. That keeps Hanaka’s wide display looking deliberate while still giving the entire collection a chance to be featured.
