About This Product

If you're prepping slides for microscopy, these round cover glasses from ZTBH are exactly what you need.

You get a box of 100 pieces in various diameters – 3mm, 4mm, 5mm, 6mm, all the way up to 10mm – so you can pick the right size for whatever specimen you're mounting.

Each one is just 0.

13 to 0.
17mm thick (that's about 0.
006 inches), which is the standard for most biological and educational work.
They're made of clear optical-grade glass, so they let light through cleanly without distortion.
Great for schools, labs, or just messing around with your home microscope.

Use 'em to protect your objectives, flatten samples, or make permanent mounts.

They're small, easy to handle, and come in a handy box so you don't lose 'em.

Just be aware that monitor colors might vary a bit, and there could be a tiny tolerance in diameter – but for everyday lab use, these are solid and affordable.
