If you have tinted windows inside stickers do not show up outside well. I much prefer a sticker for the outside. Also, reverse stickers can only go on relatively clear glass. A normal sticker can be placed on a laptop, refrigerator, bumper, etc.

Those are decals and not stickers. Have been a member since 2011 and have never seen TT decals. With todays dark tinted windows doubt that decals would show through the windows. Do not see many decals on the inside of vehicles in todays market or at least those that are recognizable. I tired to put a white one on the inside of my SUV and could barely see it. Took it out. I for one am happy with what we are getting. TT sticker on the back of my SUV window and has held up well in our crazy weather conditions.

Is a decal the same as a sticker?

Decal vs Sticker: Pros, Cons, and Key Differences Explained ...
Yes, a decal is a type of sticker, but the terms often imply different characteristics, with stickers typically being simpler, all-in-one peel-and-stick items for smaller uses, while decals (short for decalcomania) often refer to more durable, multi-layer graphics (like vinyl lettering with transfer tape) designed for larger applications like cars, walls, or windows and built to withstand weather. Essentially, all decals are stickers, but not all stickers are decals, similar to how all squares are rectangles, but not all rectangles are squares.
