This kit was amazing and came with enough stickers for two poster boards making it a good value. The letter size paper is printable sticker paper which makes the process of assembling science fair displays totally mess free!Pro tip: Some of the smaller stickers are easy to move around if you make a mistake but the full sheets require a bit more care—the sticker paper can stick to itself so make sure you only peel one side of the sheet off, and get it aligned and in place on the board, before un-peeling the remainder of the backing.
