Cup capacity is not guaranteed to be exact. If it is critical for your application, please purchase one first to test out. Also, it can change between batches and we may not notice the slight change. Initially, we did NOT measure to the rim.
Please keep in mind that these are low cost "novelty" items. At wholesale, you are paying in the range of $1.50 per cup, which includes the cup, electronics, LED bulbs and usually three batteries.
Cups are plastic, and scratch easily. Please do not use abrasive pads to wash the cup.
Sometimes the button will get "stale" from storage and pressing it a bunch of times repeatedly will get the cup to work. This should take care of about half of the apparent duds.
In some cases, batteries may start to leak. This should not make up more then a few percent of the batch. In most cases, removing the batteries and wiping them clean on something abrasive, like on denim, will fix the corrosion issue for the few cups which are still dead after exercising the button.
On a rare occasion the cup will end up turned on and the batteries will drain.
It is very rare for the cup to actually be defective.
You should expect roughly a 3% dudd rate in any of the wholesale lots, (but it can vary depending on the item,) and so budget for it when placing your order. If you are ordering for an important event, please keep in mind that these are inexpensive novelties and you should consider purchasing a sufficient margin of extra product. Please keep in mind that this small dudd rate is expected and is reflected in the whilesale price. We will certainly replace any major defects, but few dudds are part of the package and can not be replaced as part of our guarantee. Thank you for your understanding.
We offer imprinting on all of our barware. We do this in-house and can offer fast turn-around time and low minimums of just one case. Please see the Custom Imprinting category for details. Imprint area is roughly 1.5" circle. Imprint is single color. We will post some photos of the work we have done so far soon.
