These molds are the best sized bath bombs I have found. The inside diameter is just slighter wider than 2.5 inches (I have also tried the 2.75 inch molds, but that much bath bomb mix added to the tub caused itchy skin).

Package was very well packed, arriving in Canada (after surviving customs) in perfect condition.

For clam-shell molds, they are very well made and sturdy.

The molds are a bit snug to fit together, but if you are using them as packaging in addition to molds, then they should be snug to stay together.

These molds made my bath bomb projects come to life! So glad I found them here!

I use a 2.75” stainless steel mold for my bath bombs and when doing them by hand it is hard to find something for them to dry on that doesn’t give them a flat spot. I LOVE these. I make my bombs in the SS mold then transfer it to the plastic cup and I don’t put the lid on mine so I get double the amount to make sure my bath bombs are completely round! They rinse off easily and I’ve not experienced any scent transfer either.

these molds are pretty much what i expected: a cheap, plastic alternative to metal molds. they hold up pretty well and are a bit sturdier than i thought they’d be. overall, a good bargain. i do have one qualm: one of the mold halves i received was squashed. it was only one out of the two orders i placed but more care could have been taken to weed it out.

So I brought these awhile ago as a STEAM DIY sensory friendly Girl Scout project idea. I’m just looking the molds over for the event and I’m confused since they’re all the same size - how do I get them to close? The display photo looks like they snap together, am I misunderstanding the picture? I did the 3stars since I’m unsure if my set is correct...

I liked the size, but hard to unmold once filled. The plastic is flimsy and dents easily. I ended up using my old molds.

I bought these to shape the bath bombs, not to seal up and deliver as part of the bath bombs. They worked very well for the way I intended to use them. I wasn't able to cleanly close them, so what I did was fill each side, pack it down, add a pile more filling, close up as much as possible, twist back and forth to get rid of most of the excess, and squeeze a bit to make sure the bath bomb didn't split down the middle. Then I took one of the two lids off and set the bath bomb out to dry. Once dry, most came out of the other plastic piece easily. About half had to be twisted and tapped a bit to get the bath bomb out, but they did come out. My plan is to put the completed bath bomb in cellophane and wrap a ribbon around to close. So, for my purposes, these worked well. I'm sure other people were successful at closing theirs properly, but I want to re-use these. I've seen reviews suggesting they are flimsy. If they were thicker, I think it would be harder to get the bath bomb out, so I'm ok with the thickness. Thin plastic like this will not last forever - I have soap molds that are thin plastic and eventually they break. But the price was good, so I'll replace them if they break apart over time.

These plastic bath bomb molds are a bit small but they are pretty good to use. The best part is my bath bombs do not break. Pretty good for the price.

I bought these thinking they would be great to use so I wouldn't have to wrap my bath bombs. I had a few issues with them. When filling them up it's hard to get them closed, the filling fills the outside area that is smashed and it looks messy. They do dent easily, and again, don't look nice. They are also very hard to get open-which is a good thing but the pressure you use to try and open them cause them to break apart. Not good. One thing I did do was use a similar size metal mold and then once I got it done placed it in this mold because I have them now and used it that way. Looked nice for display, it is what it is. I will not reorder this product again, it's just not something I want to mess with anymore.
