Here is a Bob the Builder baby blanket that's been used for 18 years, next to a new one — and sorry to the owner, but the left one is giving single-ply toilet paper.

1

This kneaded eraser is making me nostalgic for grade school, when opening a new one after completely blackening your old one was one of the top 10 most satisfying things on the planet.

2

The wallet on the left was used for six years, and the one on the right is brand new. This is why every holiday gift guide for men has wallets on it, people.

3

Here's a new Pikachu plushie next to one that's been used for 15 years. Poor guy is also missing his hat, but maybe he left it in his Poké Ball.

4

Here's what a new vs. a full sketchbook looks like, and I don't know why, but this is immensely satisfying to me.

5

Here's what a cookbook that's been well loved for 14 years looks like next to a new one. The old one may be a little worse for wear, but the ingredient stains next to your favorite recipes add character, IMO.

6

Here is an old clog next to a brand-new one (though I'm willing to bet the old one is MUCH comfier; I can't imagine how long it takes to break in clogs).

7

I'm not gonna advocate using a mesh loofah for five years, but in case you were curious, here's what a new loofah looks like next to one that's 5 years old.

8

The running shoe on the right is only 2 months old, compared with the new one on the left, so I'm gonna go ahead and congratulate this person on running the New York City Marathon, because this is truly impressively worn down for only two months. Also, did they step on a nail???

9

Can you guess which pair of sneakers has been used for seven years? This is a hard one.

10

And can you spot the 15-year-old hammer? (Bet you weren't expecting a pop quiz, were you?)

11

This person was lucky enough to find a new version of their childhood bear at a flea market, and let's just say that there were a couple of small differences between the two.

12

This person finally replaced their desk chair after eight years, and it's giving me flashbacks to my dad's super-old home office chair that he kept until it was falling apart.

13

This photo of a new air filter vs. an old one from Shanghai is making me cough just looking at it.

14

And this 5-year-old pan next to a brand-new one is making me want to buy an all-new set of pans.

15

This new phone case next to a 2-year-old one is DEFINITELY making me worry that my nasty old phone case needs replacing.

16

Sorry if you've got a retainer, because this new vs. old retainer pic is definitely gonna making you think about replacing your old one, and I know they don't come cheap.
