Royal Massage Glass Fire Cupping Jars Thick Glass Cupping Set 4 Sizes Vacuum Cupping Glass Fire Cupping Jars with Finger Grips (12 Pieces)

thick, good quality glass. I would recommend.

The quality of the cups are thick and can withstand dropping or if it accidentally falls off, it won't break like the previous ones I had. Quick delivery as well. I got them t days before date given. I will buy again.

Good value. Works well.

Work great and a great size! The finger indentations help with holding them when applying. Just don’t know why the odd number?

The quality is not bad, but it's a little smaller.

My therapist love this cuppings they perfect size for men.

I received my cups and although I wasn't exactly overjoyed with the packing, they were individually wrapped and in packing peanuts. Two of the extra large cups had a weird veining/cracking that make me a little unsure if it was safe to use them. I emailed the vendor directly through Amazon and they were extremely quick to respond. All they asked for was a picture of the defect and within a total of two hours, I had new cups on the way to me. Granted, if it was a defect, it shouldn't have left the warehouse but the company was extra quick to make sure I was satisfied and had what I needed. All in all, it was an excellent transaction. I'd buy from them again.

Inaccurate description the listing states that the set of 24 contains sizes #1 - #5 but only came with 24 of #1 all the same size.

These are plastic not glass. They need to be glass to work

This is a super expensive cupping. From the picture, I thought I'm receiving 5 of them but it is only one. I was not careful enough to read the details when buying it, but the picture is deceiving.
