But you'll use it most often for writing letters; reports; or anything else you'd want to Braille on a regular 8.5" by 11" sheet of paper. Our Standard Slate also has the slots in the top which allow you to Braille on labeling tape. Plus; this slate's rugged; all-metal construction has earned it best-selling status among all of the items in our entire Braille writing equipment product line. Because our Standard Slate lets you write only four lines at a time; you do have to open it up to move it down the page every few lines. But you sure can't beat this slate's small size; which makes it wonderfully portable! Style: Now it's time to decide whether you want your new slate to have pins up or pins down. Pins Up: Very briefly; this is the usual style. The four pins that hold the paper in place are on the bottom of the slate; which is the way all our other slates are. This design makes it faster to move the slate down the page to continue writing. (If you're at all unsure which type to get; just go for Pins Up - it's the norm.) Pins Down: This means the four pins that secure the sheet of paper are on the top of the slate. Many beginning Braille readers prefer this type of slate because it's easy to proofread and make corrections if necessary. Just flip the slate over; lift the top; and read what you've written. The pins will hold the paper steady while you read or correct mistakes.
