Summo is a compact refillable pod brand built on one device and its refills. The Summo Pro 1 kit is the entry point, a simple pod system that ships as a single unit, and the Dual Resistance Pods come as a box of 5 three-packs. That is the whole range, which makes it an easy line to carry.
The trade logic is the usual pod story. The device sells once and the pods sell for as long as the customer keeps it, so the money is in the refill, not the kit. The dual-resistance pod is the useful part for a shop: one pod covers both a tighter mouth-to-lung draw and a looser one, so you stock a single consumable rather than two. Being refillable, it runs on nic salts the customer buys separately, which is a second attach at the same counter. There is no minimum order, so a device and a box of pods is a valid first order. As a two-line brand Summo is a budget pod option, not a range to build a wall around.

The Pro 1 kit ships as a single unit and the Dual Resistance Pods as a box of 5 three-packs. There is no minimum order, so one device and one box of pods is a valid order.
It is a refillable pod kit, so it takes 10ml nic salts the customer buys separately. Stock a few popular salts alongside it to capture the refill sale.
