Scientific Labwares Disposable Punch Biopsy with Protective Cap, 3.5mm, Sterile, Single Punch Blade, Indivdually Packed (Box of 10)

This item worked perfectly as it is intended and allowed me to deliver the necessary biopsy samples to the laboratory in professional condition.

Very good product

I used this for a big cyst on my breast that wouldn’t come to a head on its own, so I bought this after watching many videos on YouTube . I did use numbing cream but honestly didn’t help but I still had to brave and cut my own self . U have to keep twisting counter clock wise and eventually you feel the skin separate and untwist it back out . It does hurt a lot but I couldn’t deal with the cyst pain . Did this back in November of 2022 and now it’s January 2023 healed up nice . I used peroxide , Neosporin and a bandage and cleaned it every few hours . ITS WORTH IT , THE DOCTORS WILL DO THE SAME AND CHARGE U A WHOLE LOT WHEN U CAN DO IT YOURSELF!

These are very sharp and word great for tissue punching to uncover an implant.

I purchased two packs of 4-mm and 6-mm disposable puncher. Each puncher is individually packaged with protective cap. The cutting edge is sharp to cut soft polymer samples. The diameter is as accurate as described. Only knob color is different from the image showing in amazon, but it does not affect its use.

This does not do a punch, it cuts a circle around your lesion, you have to use tweezers to pull up cut skin and cut it yourself with scissors or razorback. I thought item would do a scoop out and it does not.

Good for price but they’re not as sharp. I’m a professional body piercer so I used them for doing microdermal piercings, these are a little bit of a struggle to perforate through the skin. Still works but just keep that in mind.

Sharp and with a good sized handle. Do the job at the right price.
