This keyguard fits the AlphaSmart Neo2 word processing keyboard. It is usually labeled "Renaissance Learning Neo2" on the back.
Material - The default material is 3/16" clear acrylic. If you need a thinner keyguard, you can choose 1/8" acrylic styrene, but it makes for very shallow key openings. Alternatively, there are a number of 1/4' materials you can choose which leave deeper key openings and give you lots of choices for color. Personalize your keyguard with an unfinished wood for an old-world or executive look.
