The Post-it FAQ: Labeling & Cover-Up Tape, Office Math, and the Weird Searches That Land Here

If you searched for "is a post bacc worth it for medical school" and landed here because of an autocorrect hiccup—let me save you the back button. This page is about Post-it products, specifically the labeling & cover-up tape. But I also get searches like percent decrease calculator, creatinine clearance calculator, and how to check ink levels on hp printer. So I'm going to answer all of them, because an organized office is an organized life.

Quick background: I work on the quality side of the office-supplies business. I review Post-it-branded items before they ship—roughly 200 SKUs a year. Maybe 180, I'd have to check the system. In Q1 2024, I rejected about 6% of first deliveries because the specs were off. So when I talk about what these products can and can't do, it's not marketing fluff.

1. What exactly is Post-it labeling & cover-up tape?

Basically, it's a long, thin sticky note. It's a repositionable, removable adhesive tape with a matte finish you can write on. It comes in widths like 1 inch and 2 inches, and it's great for labeling folders, binders, file tabs, cables, and even whiteboards.

One thing I've learned in quality control: "removable" and "repositionable" don't mean the same thing to everyone. I once said "removable" to a vendor, and they heard "repositionable." Discovered the difference when a batch of labels peeled off during a client presentation. We were using the same word but meaning different things. So to be clear: Post-it labeling tape is designed to be removable without damaging most surfaces, but if you need something that'll survive shipping or direct sun, test it first.

If you're labeling durable file dividers, the Post-it durable filing tabs are a better bet than plain tape. They're made to handle more rubbing and pulling.

2. Is a post bacc worth it for medical school?

Honestly? That's not my lane. I'm the person who checks whether a highlighter bleeds through paper, not whether your GPA needs a comeback. But you're here, so let me make it useful.

"Post bacc" and "Post-it" are one letter apart, and that seems to bring a lot of pre-med students to office-supply pages. If you're in a clinical setting, you're more likely to need a creatinine clearance calculator than a sticky note. But while you're here: the Post-it highlighter with flags is a genuinely useful thing for studying. Highlight a paragraph, pull the little flag tab, and mark your question for later. It's not a medical school admission strategy, but it might save you from another read-through of the same chapter.

And if you're labeling lab notebooks, use the durable tabs. Regular sticky notes in a lab coat pocket? They'll be gone before your shift ends. I say that from experience.

3. How do I use a percent decrease calculator for office supplies?

You don't need a special tool. The formula is:

Percent decrease = ((Old value – New value) / Old value) × 100

Say your team went through 12 cases of Post-it easel pads last year, and this year it was 9. That's (12 – 9) / 12 × 100 = 25% decrease. Weirdly satisfying when you're doing a budget review.

The mistake I see a lot is people divide by the new value instead of the old one. That gives you a different number and makes the savings look bigger than they were. I've sent procurement spreadsheets back for that exact error—okay, "rejected" is a strong word, but I did write a lot of red comments.

4. Creatinine clearance calculator? What does that have to do with Post-it?

Nothing directly. But if the search term brought you here, I'm guessing you're a clinician or a pre-med student. The Cockcroft-Gault equation is:

CrCl = [(140 – age) × weight in kg] / (72 × serum creatinine in mg/dL)
For women: multiply the result by 0.85.

Now, a more office-relevant point: if you're labeling specimen tubes or anything that's going into a lab machine, do not use repositionable tape. Use lab-approved labels. Post-it labeling tape is for things humans handle—file folders, name badges, shelf labels, cable labels. The moment something needs to survive a centrifuge, that's outside the spec. I've seen a batch of 8,000 units ruined by assuming "label tape" worked for every label job. Different material, different adhesive. Don't learn that one the expensive way.

5. How to check ink levels on HP printer

This one is easy, and it's probably why you're here.

• Open the HP Smart app on your computer or phone.
• Select your printer, then look for "Supply Levels" or "Ink Levels".
• On the printer's control panel, check the ink/toner icon or the "Supplies" menu.
• For network printers, open a browser and enter the printer's IP address. Go to the Embedded Web Server, then "Supplies".

Pro tip: keep a Post-it flag on the printer that says "Replace cyan soon" before the alert starts showing up at 9 PM the night before a deadline. Saved me from a lot of last-minute runs—or rather, it saved my team. I still keep a stack of Post-it labels in the supply cabinet for exactly this.

6. Can I order Post-it products in small quantities without getting ignored?

Yes, and this is something I care about. In this industry, small orders get pushed aside too often. I've seen a $200 order treated like a favor. That's backwards. Today's small customer is tomorrow's large account.

When I was starting out, a vendor treated my $180 order like it mattered. They even called to check the color profile. I still buy from them a decade later. Small doesn't mean unimportant—it means potential.

If you're a small business or a solo buyer: order the samples, order the five packs of label tape, order the one whiteboard. The quality checks are the same. The batch gets inspected, the adhesive gets tested, and if there's a spec issue, it gets caught before you buy it. At least, that's how it's supposed to work.
