With this particular clay, however, it was a bit tricky to produce a product that actually erased. After much trial and error, we determined that the erasibility of the product was dependent on the baking time. Per Sculpey.com:
"Bake at 250 °F (130 °C) for 15 minutes per 1/4 in (6 mm) thickness. DO NOT MICROWAVE. Baking should be completed by an adult. DO NOT EXCEED THE ABOVE TEMPERATURE OR RECOMMENDED BAKING TIME"
Those familiar with "normal" Sculpey will notice that this is NOT the same temperature as usual.
One factor which could lead to a less than ideal eraser is the calculation of the baking time. The designs that we came up with were rather small neither of my girls seemed to want a brick/paperweight sized eraser...picky, aren't they. Anyway, smaller size = smaller parts, of varying sizes and thickness. It is difficult to determine the bake time of, for example, a strawberry that is an inch at the top, tapering down to an 1/8th of an inch at the bottom. Add to that the leaves and stem, each with their own thickness, and you end up needing a degree in advanced calculus just to determine a proper baking time.
So, purchase this product knowing that:
1. Over baking ='s no erasing.
2. Determining an ideal bake time involves a learning curve.
3. Once #'s 1. and 2. are overcome, this stuff makes wonderfully fun erasers, sure to generate the admiration of one's peers and a possible sales opportunity for your kids.
And, finally,
4. Sculpey is rather chintzy with this clay. Don't expect to get that much of each color.
All in all, I would still recommend this product for children 7-8 and above.

My grand daughter likes crafts. There seems to be plenty of this Sculpey clay to keep making erasers for days. There are many colors to use, and every day when we speak on the phone, she tells me what new erasers she has made. I am particularly pleased that there seems to be enough clay to last a long time. I tried the erasers, and I have to admit I have used better erasers, but they will erase.
