Buying Guide
Suggestion boxes help gather ideas safely. They boost team input without worry. Pick the right one for your needs.
I set up a suggestion box in my office years ago. It sparked great ideas from shy team members. Now, I always recommend them for open talks.
- 
Material: Choose strong materials like metal or wood for lasting use. Plastic works for light needs but may break easy. Pick what fits your spot to avoid quick wear. 
- 
Size and Capacity: Look for a size that holds your items well. Small boxes suit desks, big ones fit walls. Check dimensions to match your space. 
- 
Lock and Security: A good lock keeps contents safe from peeks. Get one with keys or combos for easy access. This builds trust in your setup. 
- 
Mounting Options: Some boxes mount on walls, others sit on tables. Pick what suits your area best. Easy install saves time and hassle. 
- 
Slot Design: A wide slot lets drops go in smooth. It should take cards, notes, or coins without jams. Test fit for your items. 
- 
Extras Included: Many come with cards, keys, or signs. These add value right away. Look for bundles that cut extra buys. 
- 
Durability and Finish: Tough builds resist dents or scratches. A clean finish looks pro in any room. This keeps your box neat over time. 
- 
Price and Value: Balance cost with features you need. Cheap ones work for one-time use, pricier last longer. Invest in quality for best results.
