Why Waterproof Index Cards?

Waterproof Index Cards Made of Plastic

Why would anyone need waterproof index cards anyways?


Waterproof Index Card

Our ProSimpli index cards can be completely submerged in water to clean. You won’t have to worry about water seeping through some weak spot in the cards and ruining them.

A lot of index cards claim to be “waterproof” but are made with laminated cardstock (paper-like). This isn’t a bad thing. However, if they bend or get creased, their waterproof ability quickly deteriorates.


Dry erase or wet erase markers work!

If you are a student in college, you probably go through a ton of index cards. Sure, index cards aren’t expensive but if you could reuse your index cards, save money for years to come, and help reduce waste, it’s a win-win.

If you’re worried about smudging, we recommend using wet-erase markers.

Wet-erase markers are different from dry-erase markers in that once wet-erase ink dries, it can only be wiped away with a damp cloth whereas dry-erase ink rubs off easily.


Our index cards are 3x thicker than standard index cards. When you hold them, you can feel their strength. This makes them great candidates for long-term use.

Just think of each index card as a mini whiteboard. They literally are made of the same whiteboard material!

Waterproof Index Card Ideas

When our customers talk, we listen. Here are just a few ideas that our customers have told us about.

Fill-in-the-word Games

Fill in the blank word game

Some teachers use them as fill-in-the-blank word games. They use permanent marker to write or draw something that can’t be washed off. Then they give it to their students to fill-in-the-blanks.

This teaches younger learners how to write and think creatively while having fun.

College Students

College students

Several college students have written us telling us how much they love being able to reuse their index cards. They have used them for school presentations, studying, brainstorming, collaboration in group activities, and the possibilities go on and on.

Daily TO-DO List

Just ONE card can be your daily to-do list card to keep you on-track for hitting your goals. Journals are great for this, but having your to-do list in a small compact form helps you focus on the really important things to get done in the day.

We aren’t just saying this, we practice what we preach! It works, and is nice not to have a bunch of old crossed-out lists lying around. Nice and neat!
