I didn't know that, so thanks!

I guess my confusion would now be Why Would They Give Themselves That Restriction, though. It seems like they're leaving a stupid amount of money on the table, while nearly every other aspect of Bandai's merchandising arms are churning out products for that year's Rider. To sort of declare the model line Heisei Only... why? What is the point of that?

Legend Riders are a bit of a commodity right now. The currently airing series is ALWAYS going to have merch and representation - that will never be a problem. Same can't be said for Heisei, especially since we're a year into Reiwa.

Right, could someone tell me what the difference between stickers with these guys are?

How do you mean?

I mean like there's the normal stickers and there's the green-backed ones. I'd like to know what the difference is in the latter ones.

Just checked decade the green-backed ones should be water slide decals they are a bit like stickers but are very different in how they are applied. I believe ex-aid came with a full set in both so that you could choose what was best for your building experience.

There are no water slide decals in the box. Both of sheets are adhesive stickers, but usually the difference is the material or finish.

Ex-aid comes with metallic foil sticker sheet, and an identical matte semi-transparent sheet. It's kind of like, choose whatever you think is best for the part.

The clear ones often have unclear edges so you wouldn't want a print to run up to the edge, or they are taking advantage of some clear effect like a gradient or shine-through (See Hibiki's arms stickers).

oh, thank you. I would have kept trying to use water to apply later ones.

So, you're telling me there's no permanent way to keep the details into the kit?

What do you mean? Something like Ex-Aid's chest is always gonna be a sticker. We all loathe stickers, but sometimes its the only way a kit can be released.

No one (that I know of) makes water slides for the Kamen Rider Figure Rise kits, and if they did, they'd would not perform well because of all the organic and curved surfaces they go onto.

You can always use a top coat spray to "seal in" many of the stickers.

Model kits are inherently less permanent than figures or statues. The best thing you can do to preserve them is handle them less, display them properly, and maybe use paint where possible.
