Magic Tricks

I've heard that you can get the parts (refills), but that would be very unusual for a trick's gimmick in this price range.
Simply, regardless of if it can repaired, it's usually a better value just to buy another trick and get the new gimmick.
Candidly, if it's a great trick for you, then $24.95 is a small price to pay for another trick or even a 'back up'.
Yes, gimmicks break...and most can be repaired/remade because now you know the secret.
However, some are just easier to repurchase.
Oh, I don't see anything referencing a 'refill' for Sleeper here at PM.
Good luck!
