the deck is part of the gimmick, but i can transport that to every kind of cover (phone, boxes), or use hands but in that case it would be less clean.
Yeah i meant to do that with candies with different colours, but i didn't have any, so i use the closer chocolates i had in my house.
I'd like to build a routine with that, maybe changing the deck with a chocolate box.
I also like the flower idea, because it brings magic "outside of the box" and uses things other than cards and coins
If nothing else, consider making a gimmick that's in the shape of a popular chocolates brand instead of a pack of cards. Magicians "in the field" rely on playing cards a lot because of their low cost, ubiquity and popularity but it's nice now and then to be able to do something that's completely free of them. Cups and balls don't always play well and require a table, foam balls are a bit "old school" for some, coin magic can be expensive if you use shells or vintage coins, cigarettes are becoming societally less acceptable (and were never healthy to begin with), so often, a magician will grab a pack of cards as his go-to prop - not necessarily a bad thing, but it's good to change it up now and then.
If this gimmick becomes something you want to sell, consider where you're planning to sell it. Chocolates and candies can be a very regional thing, so the packaging will vary from place to place and (assuming you make a candy-package gimmick to replace the deck) you'll want to customize the gimmick to match the common locally-available candies. For example, we have Kit Kat bars in the US, but the packaging is extremely different from those sold, for example, in Ireland or the UK.
Candy-bar gimmicks might seem too small for what you want to do with them, but consider that (at least in the US) the candies sold in movie theaters and some retailers are available in "king size" large packages as well as the standard size. Such a large package allows you more options in terms of how you ultimately build and use the gimmick - for example, you might be able to make a gimmick that can "steal/switch" more than once, leaving different candies behind with each pass. Better still, there's also "bite size" versions of many candy bars, individually wrapped - these are often packaged for Halloween treats to hand out to kids, but are often available year-round as well. Create one "jumbo bar" gimmick with several "bite size" candies and you could practically build an entire routine into that one kit!
