AJMD KBuilt from Solid Metal, Handled with Care
AJMD K started because we were frustrated by the flood of cheap plastic dumbbells filled with loose sand and concrete. When those shells cracked, they ruined floors and ended up in trash bins within months. We wanted real, solid iron free weights built the traditional way.
We partnered directly with casting foundries that work with Class-30 grey iron and solid cold-rolled steel. Our dumbbells are cast, machined, and checked one by one on digital warehouse scales before they are packaged into double-wall cartons.
We sell directly to lifters across Japan without distributor markup. Every shipment is handled carefully, supported by transparent payment options like cash on delivery and bank transfer, and backed by a straightforward 30-day return policy for unused gear.
Real Solid Metals
We use grey cast iron and cold-rolled steel exclusively. You will never find sand, concrete, or loose fillers in our weights.
Every Unit Weighed
We test dumbbell pairs on digital scales before taping the box. Your left and right hands lift the exact load stated on the casting.
Direct Honest Service
We answer customer emails directly and pack heavy boxes securely so your delivery arrives intact without courier damage.
Our Production Standards
We inspect every dumbbell head for smooth casting and verify weight on commercial scales. Each shipment is secured in thick double-wall cartons with custom foam edge blocks.
We build cast iron dumbbells without plastic fillers, sand, or weak seams. Every piece is weighed and checked by hand before leaving our shop.
