The Guessing Jar
A gallon of candy, counted and sealed. Nobody knows the number — not even you — until the envelope is opened.

How it works
Step 1
Pick your candy
Choose the fill your crowd will love — the choice is yours, the count is ours.
Step 2
We fill it, count it, and seal it
Every jar is filled, counted, and sealed by Sweet Trolley before it ships.
Step 3
Open the envelope when the contest ends
The official count stays sealed until you're ready to crown a winner.
Pick your candy
We fill, count, and seal — your pick sets the difficulty, not the number.
Add a custom label (+$10)
Brand the jar for your event, school, or booth.

Shipping & timing
- • Every Guessing Jar is made to order and ships in 7 business days.
- • Shipping included to the contiguous US. Alaska & Hawaii add a flat $10 per order.
- • Packed in a double-wall box so the jar arrives contest-ready.
- • Candy settles in transit. Your jar is filled to the top when we seal it, and the count in the envelope is the count in the jar — a little headroom after shipping is normal and doesn't change the number.
- • Arrived broken? Send us a photo within 48 hours and we'll ship a replacement.
