Shell looks great, and it's a good price. I'm a beginner with multiplying balls, so I appreciated this inexpensive, yet good-looking option.

The trick has a gimmick that is made to last. It comes with four sponge balls and of course the gimmick.

THis trick takes about 2-4 days to learn and about 1 week to master especially if you have small hands. instructions are clear and include many details that are helpful.

I do not like the angle sensitivity with this trick as it is a very big spoiler in magic.

Great trick for stage or street performers.

this effect looks amazing when done right, but it will take tons, and tons, and tons! of practice, if not done right it can look UGLY! i still haven't mastered them, but i don't practice them much, i work with other tricks, but anyway, the sponges are the perfect squishiness for the way you're manipulating them, and the secret shocked me at how simple it really is!
it is a great effect when done right, but you better practice hard before you perform it somewhere!
