Milliron Tools – We have been making this tool in a pliers version for many years. Now we are making them as tweezers. Just as wonderful a tool, but at half the price of the old pliers version. These clever little mashers press a blob of molten glass into a delicate, bead scale fish fin, two fin bones wide at a time. Just heat the glass and mash it side by side repeatedly to make a wider and wider fin.
