New products added to the "irelu Binder Series", "irelu PVC Refill Series", and "irelu Sleeve Series"
This 6th release introduces a total of 8 new items: two types of "irelu (irelu) Binder Slim White/Black", three types of PVC refills, and three types of "irelu Sleeves".
irelu (irelu) Binder Slim
- With a slim body of 42mm spine width, it is approximately 20mm thinner than the existing irelu binder (60mm spine width).
- It does not take up much space even when multiple binders are lined up on a shelf, making it an ideal size for managing collections separately by work or type of goods.
- The D-ring 4-hole mechanism remains the same, compatible with existing irelu refills and A4 wide refills from other companies.
- Available in two colors: White and Black.
irelu (irelu) PVC Refills
- irelu PVC refills use white backing paper, preventing the items below from showing through when refills are stacked, beautifully highlighting collectible goods.
- The soft PVC material allows for smooth storage of even thick goods, and all pockets are equipped with a flap to prevent precious collectible goods from falling out.
- The newly released "1 pocket" refill accommodates large acrylic stands up to A4 size (210 x 297mm).
- The "12 pockets" refill is perfectly sized for 57mm can badges, neatly storing 12 pieces per sheet.
- The "15 pockets" refill has an optimal inner pocket size for 44mm can badges, allowing for organized storage of 15 pieces per sheet.
irelu (irelu) Sleeves
- The "irelu Sleeve" series, launched simultaneously, introduces three types: "for PVC 3 pockets", "for PVC 4 pockets", and "for 44mm can badges".
- All are made of highly transparent 0.05mm thick OPP material, protecting the colors and details of goods without compromise.
- With adhesive tape, the height of the stored goods can be perfectly sealed by adjusting the tape position.
- Furthermore, they are designed to fit the inner pocket dimensions of compatible irelu PVC refills, allowing goods to be stored in the refill while still in their sleeves.
The corresponding refills and uses for each sleeve are as follows:
- For PVC 3 pockets: Compatible with "irelu PVC Refill 3 Pockets". Ideal for protecting tall acrylic stands.
- For PVC 4 pockets: Compatible with "irelu PVC Refill 4 Pockets". Ideal for protecting acrylic stands up to postcard size.
