I live silicone. Its made removing items so much easier. I use to use the plastic and temoving the products was more difficult and they would often break. These bend and stretch allowing things to pop right out. I love using these for small sized lotion bar cubes and for bath bomb squares. The big round ones are often too large and people have to break them and use peices which is messy. This makes perfect sizes single use bathbombs people can use one or two depending on what they like, without crumbling bomb ball all iver the bathroom. #RankBoosterReview ii. #Sponsored iii. #Moldiy
