Convenient but issues with size

This is the second time I've ordered sticker packs; both times I never had any idea what the dimensions (in cm or inches) would be for the final product. Based on the two previous orders, output sizing seems random. I love the sticker packs-they're super convenient, the colors are great, and they survive the elements outside, but it's a bit frustrating to not have any info on what size stickers I'll receive. I'm not sure I'd order these again without advance guidelines because of this issue. Otherwise, the stickers themselves are great.
