The last wearable kit we sold was not one that we were very happy with.   Too many poorly made parts, lower quality etc.   So we have now made our own new kit!   Genuine brass tube, with brass end caps, and then electroplated for a lasting and beautiful shiny finish.   The chamber uses glass disks on both ends; a frosted disk on one end and clear on the other.   Genuine front surface mirror of course.  Glass magnifying lens, and real glass colored bits - a mixture of faceted gems and other translucent pieces.  All you need to add is the chain.
Note: Not great for young children! Because there is a chain, it could pose a strangulation danger to young children. We recomment using a breakaway chain or magnetic clasps.
