This catalog is wholesale-oriented. Typical tip lines start around 50–100 units, with increments that keep packing and carton counts clean. Exact minimums appear on each SKU — always follow the number on the product page.
You can mix tip types in one order (for example 36-pin and Nano-S for the same pen), but each type must meet its own minimum. Combining two undersized lines into one "total" does not unlock pricing or packing.
If you need a trial quantity below the listed minimum, say so in the order notes or open a sourcing request. We will tell you honestly whether a smaller run is possible for that tip.
