Updated September 14, 2026 · Research-based review
Our verdict
This six roll set from MoHern suits anyone building a first bonsai wiring kit, since it covers thin twigs through thick branches with one purchase. The main strength is the 1mm to 4mm gauge spread across 152 feet. The trade off is that you still need to buy a separate wire cutter.

Who this wire set is for
MoHern's six piece bonsai wire kit is built for hobbyists who are assembling their first proper wiring supply rather than buying single rolls as they go. Because the set spans six gauges from 1mm up to 4mm, one order covers delicate shoots, mid size limbs, and heavier trunk work without hunting down extra rolls later. That range matters more than it sounds, since a grower with only one or two wire thicknesses on hand tends to either under wire a branch, which lets it spring back, or over wire it, which can scar the bark. Anyone training junipers, ficus, or other common nursery stock into their first bonsai shapes will find this set gives enough material to practice on cheap material before committing to a prized tree, and the black finish keeps the wire from standing out once it is wrapped around a trunk photographed for a portfolio or a club show table.
What 152 feet across six gauges actually gives you
The kit totals 152 feet split across rolls at 1mm, 1.5mm, 2mm, 2.5mm, 3mm, and 4mm, with the whole set weighing about 300 grams, so each roll works out to roughly 50 grams of wire. In plain terms, the thinnest 1mm wire suits new shoots and fine branch tips, the 1.5mm and 2mm rolls cover most secondary branches on a small to medium tree, and the 2.5mm through 4mm rolls are reserved for primary branches or a young trunk. The wire itself is aluminum rather than copper, which the listing notes bends more easily by hand and is simpler to remove with ordinary wire cutters, at the cost of holding a bend slightly less firmly than copper over long periods. The black coating is a painted or anodized finish meant to resist rust and blend against dark bark.
Using and storing the wire day to day
Aluminum bonsai wire like this is meant to be unrolled a length at a time and wrapped at roughly a 45 degree angle around the branch before it is gently bent into position, working from the trunk outward so thicker wire anchors the thinner sections that follow. Because aluminum is soft compared to copper, it is easier on the hands during long wiring sessions, which matters if you are working several branches on a bigger project in one sitting. Owners looking at this kind of multi gauge set generally keep the rolls together in a small box or bag, since loose wire tends to nick and tangle with other tools. Watch coated wire for scuffs where it rubs against rock or hard edges of a pot, since a chipped area can expose bare metal and lose the discreet black look over a season outdoors.
How it stacks up against other wire kits
Against rivals such as the Leaves and Soul Tree Training Wire Kit and the KAKURI Bonsai Wire set, this MoHern kit's strength is breadth, six gauges and 152 feet total, versus kits that ship with fewer sizes but add a cutter and canvas bag in the box. If having a cutter on day one matters more to you than gauge range, a bundled kit is the simpler buy. Against MoHern's own smaller 5 piece kit at 164 feet across three sizes, this six size version trades some total footage for a wider spread that better suits a grower training more than one tree at different stages. Compared with the KAKURI Japanese import, which many bonsai retailers treat as a benchmark for finish quality, this set is positioned as the more affordable, broader gauge option rather than the premium one.
Verdict and who should look elsewhere
For a grower who wants one order that covers new growth through a young trunk without guessing at gauges, this MoHern set earns its place, matching our score of 8.6 out of 10 for fit and value. Budget a separate wire cutter purchase, since none comes in the box, and expect the thicker 4mm roll to run out faster than the finer gauges on any tree with real primary branches to wire. Growers who prefer copper wire for its stronger holding power on mature deciduous trees, or anyone who wants a cutter and bag included from the first purchase, should look at a bundled kit instead. For most people building a first wiring supply for junipers, pines, or small tropical bonsai, this remains a sensible and versatile starting point.
Frequently asked questions
Is aluminum or copper wire better for bonsai?
Aluminum wire like this MoHern set is softer and easier to bend and remove by hand, which suits beginners and most deciduous or tropical species, while copper holds a bend more firmly and is often preferred for mature conifers.
What gauge wire should I use on a young branch versus a trunk?
Thinner wire in the 1mm to 1.5mm range suits new shoots and fine tips, mid gauges around 2mm to 2.5mm cover most secondary branches, and the 3mm to 4mm rolls in this set are meant for thicker primary branches or a young trunk.
Does this MoHern set include a wire cutter?
No, this listing is wire only across six gauges, so you will need a separate bonsai wire cutter to remove the wire cleanly once a branch has set.
