Postman Shares What Inside Of Post Box Really Looks Like

He also gave a tip for helping to avoid postboxes becoming blocked, writing: "You all seemed fascinated so here's inside one. Pls don't jam big packets in as it blocks them."

The image shows a metal basket, that looks like a large bin, with a small door in the middle.

The postie also explained how the mail is collected, writing: "Open box, bag under the chute then empty.

"Change tab to next day and voila."

One user commented saying they 'remember walking past a postie that had one open as a kid and being like WOAAAAH' to which the postman replied 'I've had kids stop and watch before'.

He continued: "Then I'll need their help to empty the letters and change the tabs over etc. If you have a job that kids think is cool, you'd have to be a monster not to wave/show them.

"Still remember a tube driver letting my kid sit in the cab for a stop after he waved as it came into the station."

One user expressed disappointment in the colour of the box's inside, saying: "I’m disappointed that the insides aren’t red too."

Another used the opportunity to get a strange confession off their chest, posting: "When I was a kid I put some snow into a letter box and then immediately realised what I did and I haven’t stopped thinking about it for 16 years."

Other users then also began confessing to mail sins with one writing: "When I was very young I had a terrible nose bleed and put the blood soaked tissue in the post box. I still have regrets 30+ years on."

They were also told not to jam the box with large letters and parcels.

One user replied that: "Postman’s probably thinking thank f*** I’ve caught the person jamming up the regular box for the past 12 months so he was probably happy to show you the inside of one."
