Strathearn designated these as Small carpet millefiori weights but I've found them ranging from about 2.25" to just under 2.7" so I've segmented them into Small from about 2.25" to about 2.5" and Medium from 2.5" to just under 2.7". The number of canes packed into these weights can range from the 60's to over 100. While these closepacks almost always had a colored ground I have seen one with a clear ground. As with many other Strathearn pwts it's not unusual to find earlier Vasart canes among the Strathearn canes. These were regular production weights and were made as needed. The more sold the more made. Produced from 1965 to 1980. This P15 series was also extended to the PP15 and PSF152 series.
