Really good for scoring. I like it much better than the plastic groove kind because it’s easy to get out of the groove. This has a metal guide with a specific scoring tool attached. I was told there are metric and inches versions, so I actually did not buy this particular item because it was metric. The inches version works for me!
Love the large scor-it scoring board. I can score my 8-1/2 x 11 for making cards before I cut it down. Makes scoring so much faster and the score mark is greating for folding.
