Buena compra! Recomiendo comprarlos si los necesitas

I use these for waxing eyebrows and upper lip. I bought this pack years ago and still have quite a bit of the strips left. Works great for me! Sometimes I double up if I put the wax on too thick because the strips are not thick. Though the pack makes up for lack of thickness with sheer number of strips. Great value!

No sirve para separar pigmentos como lo anuncian.

Looking for something cheap yet decent for chromatography experiments with my students. These were perfect. No cutting needed, nothing special we had to do but the experiment itself. Would buy again for STEM experiments in my science classes.

These chromatography strips work really well in our college biology labs to separate the photosynthetic pigments found in standard spinach leaves. A 9:1 mix of petroleum ether and acetone works as the solvent that the tip of the paper is dipped into once you have rubbed the pigments on the paper.
