The roller that reproduces the human gesture — only better.
La Batte by DdO is a patented precision craft tool that forms perfect, regular, repeatable cones — up to 13 cm, where every other roller stops at 11. Designed, 3D-printed and hand-assembled in Troyes, France. No dropshipping, no mass production: solid, durable, replaceable parts.
Ships across the EU, Switzerland, the USA & Canada. Pre-order pricing — 1,000 numbered boxes only.
A real tool, built like a fine instrument.
Many people try to form clean cones by hand and never quite manage — then fall back on ready-made products. La Batte gives you back the pleasure of making your own, with precision.
Patented & unique
A 10-point patented system (INPI FR2606195). The only roller that reaches 13 cm — and adapts to any paper length or width.
Handcrafted in France
Invented, drawn, 3D-printed and hand-assembled in Troyes. Precision-engineered parts, durable and replaceable — the opposite of disposable.
Perfect, every time
Regular, repeatable cones for legal herbs & botanicals — no skill required. If you can move a slider, you can make a flawless cone.
One method to remove all the excess. Up to 30% less paper.
The Dutch invented the cone; a French inventor perfected the roll. From the Mini to the Maxi Batte, the “French method” by DdO lets you keep only the paper you need before shaping the cone — like the “Dutch method”, but here everything happens up front. A third less paper means a smoother draw and a purer taste, every time.
