I purchased these balls as my first set of ben wa balls. Previously, I've only owned balls inside a casing, but found them a pain to clean because of having to remove them from their casing. I decided that I would purchase a cheaper set of ben wan balls to see if I enjoyed them as much as my Luna Noir beads.

These tiny balls are made of plastic. The plastic is non-porous and free of latex and phthalates. They feel smooth until you feel the seams! Each ball has a terrible seam around the entire ball. This seam is raised and sharp! I find it very uncomfortable when inside me.

As the balls aren't in a casing and have no retrieval cord; you must fish them out yourself. This can be a pain in the ass because they like to swim around inside. During their wear, as long I have them positioned just right...they are comfortable. If they aren't positioned just right...I feel very uncomfortable.

I can't tell if they actually help with my kegel exercises. I don't believe so, because I can't wear them long. I prefer to take my Luna Noir beads out of the casing and use them as ben wa balls.

Cleaning these is a breeze because they can just be rinsed after you wipe them down with a toy cleaner. Keeping them can be hard as they are so tiny. Think of the size of a die. You definitely need a carrying case or pouch for them. Otherwise they will get lost.

The best part about these is how quiet they are. No one will ever know that you are wearing them as you are standing next to them in the checkout line. You can feel the internal balls roll around when you bend and jump. But not when you don't move too much.

I would not purchase these again. I think there must be better options out there than these. They are okay at best.

The seams make these almost unusable because they are so uncomfortable. Really, I don't know why I keep them around. I can't use or recommend them.
