Note that the Creative Publications site does not seem to work equally as well with all browsers. If the above links do not work, try using a different browser.

Some individual replacement parts for the Lab Gear can be ordered from Sprout. However, you're much better off getting corner pieces from Creative Publications, as they sell ten for $8.
