If you teach cupping, the supplier behind your course kits affects more than your margins. Inconsistent cups undermine a technique demonstration, the wrong branding setup can quietly work against the training you're building, and a supplier that can't flex on order size either ties up your cash in inventory or leaves you scrambling before a course starts. Here's what's worth checking before you commit to one.
Product consistency
Silicone hardness varies by supplier, and sometimes by batch within the same supplier, in ways that matter more than most buyers expect going in. If your curriculum teaches a specific technique on a specific hardness level, an inconsistent supplier can quietly undermine your own teaching: a student practices at home with a cup that behaves differently from the one you demonstrated with in class. Ask directly how a supplier controls for this, and if hardness levels aren't something they can speak to specifically, that's worth treating as a signal.
Range of hardness and cup types
Related to the above: a supplier offering only one hardness level limits what you can actually teach. If your course covers both static and dynamic technique, you need cups suited to both, which means a supplier stocking a genuine range rather than a single general-purpose cup. This matters even more if you're building a curriculum around a specific progression, beginner to advanced, where the equipment itself is part of the teaching structure.
Branding options
This is one course creators often don't think about until it's already a problem. Some suppliers ship everything with their own logo stamped on it, which means every kit you sell is, in effect, advertising for someone else's brand instead of yours. Others offer unbranded product by default, so your course materials carry your name, not a supplier's. A smaller number go further and offer private labeling, actual custom branding on the product itself, which is a meaningfully different arrangement and usually comes with its own minimum order requirements. Know which of the three you're getting before you commit, since switching later means re-briefing students on new equipment.
Order flexibility
Course sizes vary, and a supplier that only deals in large minimum orders forces you to either overbuy inventory or underbuy and risk running short mid-cohort. Ask specifically about minimum order values (not just unit counts) and whether you can mix product types to hit that minimum, rather than being locked into ordering large quantities of a single item.
Reference materials for students
Cups without documentation put the entire teaching burden on you, including the parts, like general product care and technique reference, that a good supplier should be handling on your behalf. A supplier that provides its own reference guides, cleaning instructions, and technique documentation is doing part of your job for you and giving students something to fall back on outside of class.
Manufacturer relationship
A supplier that sources direct from a manufacturer, rather than through an added layer of distribution, tends to have more control over quality and pricing consistency over time. This is harder to verify directly, but it's a reasonable question to ask outright, and a supplier confident in that relationship will usually say so without hesitation.
Revenue paths beyond the initial kit sale
Some suppliers offer referral or affiliate arrangements for educators who send students their way for ongoing supply purchases after the course ends. This isn't essential, but it's worth asking about if you're building a program you expect to run for years rather than as a one-off course.
Where this leaves you
None of this is about finding a single "best" supplier; it's about knowing which of these seven questions matter most for your specific program before you're mid-negotiation and having to figure it out on the spot. A supplier that's strong on branding flexibility but weak on hardness range might be exactly right for one course and wrong for another.
If you're evaluating suppliers and want to see how this looks in practice, our Educator Network page outlines our own setup: unbranded product by default, private label available, a hardness range built specifically so educators can match cups to their curriculum, and low wholesale order minimums. We'd also point you to our own Cupping Set Reference Guide as an example of the kind of student-facing documentation worth asking any supplier for.
