Alice,
If the elastic coating came off easily, we would not sell the wire. :)
Our Trios collection is basically our colored wire packaged in smaller spools and bundled together - the idea behind combining the different colors of wire is that the packages reflect a color theory component - basically, if you were interested in designing a "mystical" piece or a love-themed design using multi-strands or even a single strand, you could use the Trios package that reflects those ideas - Mystical and Romance.
Our Trios wire offers the same strength and durability as the 30ft/100ft single spools we carry - just in smaller spool sizes, the Trios package is three spools of 10ft wire
If you have any questions regarding our Trios - or any of our other products, feel free to use our live chat or email us at sara@softflexcompany.com or info@softflexcompany.com.
