Calling all anime fans and pin collectors! These are insert panels for 'Ita bags' – those cool clear-window backpacks or crossbody bags used to show off enamel pins and badges. You get four PVC panels, each about 26.4x33.8cm (10.4x13.3 inches), that you can cut to fit your specific bag. They have pre-punched holes designed to hold two sizes of pins: 58mm (fits about 48 badges) and 75mm (fits about 24 badges). You just push your pin posts through the holes from the back, secure them with the rubber backs, and your collection is displayed neatly and securely behind the clear window. It keeps everything organized, prevents pins from scratching each other or falling off, and makes your bag look awesome. A perfect accessory for anyone into ita bag fashion, cosplay, or just displaying their pin collection in a unique way. Makes a great gift for anime enthusiasts too.
