Kiku wire is striving to produce the best copper bonsai wire available in America.  99.9% pure solid copper wire is professionally wound to the appropriate size rolls (larger than most) to help eliminate the hardening of the wire as you uncoil it.  This is less important in the smaller sizes which is why the smaller sizes have tighter coils.  Each coil is wound to a precise weight resulting in consistent rolls.
The wire is then taken to a professional metal hardener that has been heating metal for 40+ years.  He also happens to be a bonsai guy so he knows good wire.  Here the wire is heated to the appropriate temperature to make the softest copper in the states.  The wire is then pulled and carefully cooled through a proprietary process that significantly reduces the scale or black coating you find on some annealed copper wire.  This black scale can "spray" off the wire as you use it causing eye injury.  We do our best to keep this to a minimum, especially on larger sizes where spraying is much more common.  This also makes for a cleaner bonsai experience with less black on your hands after wiring.  If you are wiring a pine, you obviously don't care about this as your hands will be destroyed by the end anyway.

Each roll is inspected, re-bundled and tagged with a Kiku label and small wrap of Velcro to keep your wire together after the zip-ties and label are removed.

Cheaper annealed copper wire is readily available, but none that combine the quality, softness, cleanliness and love that we put into this wire.  We intentionally made this wire to higher standard. If you are looking for the best copper on the market, look no further than Kiku Annealed Copper Bonsai Wire!

Plants & Tree Shipping:
We ship bonsai trees and plants from either our parnter nursery or our in house nursery depending on the tree.  We may limit when we ship trees to help limit their exposure to extreme environments.  For example we may not ship if it will cause the tree to sit in a truck over a weekend or holiday.

Many trees are shipped by Fedex from our partner nursery in the south central united states.  Expect delivery to the West Coast to be 4-6 Business days via Fedex Ground.  To the rest of the continental USA it will take 1-4 Business Days.  Please contact us if faster shipping is needed.

If we are shipping from our Harrisburg, PA location, the tree may arrive via any carrier, but usually UPS or USPS.  Delivery is the same as above as far as time in transit.

Trees are shipped in custom boxes made just for shipping trees.  Sometimes we wrap the pot and soil in plastic to prevent it from spilling out in transit.  Many times we use packing peanuts as they have proven to be very reliable in keeping trees safe in shipping.  If a box is noticiably damaged, please take pictures prior to opening.

If you are not 100% satisfied with your purchase from Superfly Bonsai, simply contact us to arrange a return.  Items must be returned at your expense.  If you beleive that we messed up somehow please let us know and we will evaluate the situation on a case by case basis.  When a return is authorized simply send the product back in sellable condition for a full refund of the product cost.
