I bought this for a non-lab application. Specifically, racks for high quality hobby paints (e.g. Vallejo, Reaper), used for miniatures and such, are expensive and not particularly well-designed for Reaper’s “triads.” These two-for-$9.99 racks looked like they would do the job better, and they do. Order the 25mm size for these paints, use only one of the two inserts (i.e. the lower one) and if you are really anal-retentive cut the side supports down as depicted in the photo.
