Visibility was a top priority for me. I opted for markers that offered vibrant colors, ensuring that my labels stood out against the background of the test tubes. Readability was another concern. I preferred a fine tip that allowed me to write clearly and legibly, even on the small surfaces of some test tubes.

Price and Budget

While I was willing to invest in quality markers, I also kept my budget in mind. I found that prices varied significantly, so I researched different options to find a balance between cost and quality. I learned that sometimes spending a little more upfront could save money in the long run, as higher quality markers often lasted longer.
