One product and so many uses! Whether you want a ballot box, suggestion box, token box, feedback box, business card drop box etc etc, this is what you are after. Available in a range of materials and colours to suit you're usage and budget.
With so many products to choose from, how do you know if you are buying the right one? Budget obviously plays a role but don't forget the environment you are going to use your box in. For example, if you are heading to an exhibition and are wanting attendees to leave you their business card, a small clear box might be the more obvious choice, so people can see that others have left their card which encourages them to do the same. It's a similar idea if you are wanting staff members to leave feedback at work, an opaque option which is perhaps wall mounted will be best, as you need to of course leave the feedback as anonymous as possible and you might not want everyone to see how much (or how little) feedback you are getting. Larger clear boxes are popular with the likes of supermarkets or car show rooms, where they are used as token drop boxes, allowing the general public to vote on something like a good cause in the local area. For one off use or ease of transport, a collapsible pop up cardboard ballot box might be for you but remember to recycle them once you are done.
