Just wish I'd bought the multi-pack!
This refill is very easy to use, though I wish it saved a bit more on plastic. For an old-school scrapper like me, who still uses glue sticks for most of my adhesive needs, these little rollers are amazing - quick and so easy. It seems a bit expensive, though, compared with glue sticks - but the results are better and more durable. For LOs that won't just be sitting in albums/sheet protectors/frames, the rollers are great.
