The ones with black measurements on them work perfectly but the grey one washed off immediately, disappointed and they were all HANDWASHED, they were never put in the dishwasher and I use a tiny amount of Meyers clean day soap on them, and they grey ink disappeared.

Perfect little gadget to make sure I'm getting the perfect dosage each time.
Love it !
Love MaryRuth"s Organics!

I bought six of these and they arrived broken. They were stacked in three’s with no cushion between each glass. The two stacks were then well wrapped with bubble wrap. Five of six were destroyed from glass on glass contact. I contacted the seller. I used to work in packaging and shipping so I told them they need to put at least a piece of paper or thin cardboard between the glasses. They nest these together like Russian nesting dolls.
They were very sorry and responsive and shipped me a new set of six.
The very same thing happened because they packed them the very same way. They ignored my suggestion and/or the advice I gave never made it to packaging. So they gave me a refund. I’m sure there are other products they make and ship well. If I’d ordered ONE glass, it would likely have been received unbroken. And this was to be a gift. Something my daughter specifically asked for and told me where to order it.

I was so excited when I saw that Mary Ruth had this measuring shot glass. I was having problems measuring my Mary Ruth products and now I’m good!! Great idea for the products and well worth the money!!

Just don’t put them in dishwasher. The print may come off.
