No Glassware Returns

If you are unsure of what glassware you need please contact us before ordering.

Glassware cannot be returned for any reason; this is for your safety and ours. It would be prohibitively expensive to test for bacteriological, chemical or radiological agents since there is no way to tell if glass has been contaminated just by looking at it. We would have to throw it away even if you claim to never have opened the package.

However, if the item is broken, clearly defective in some way such as severely bubbled or chipped, send us an image & we will refund you.
