TIMESETL 3pcs Stainless Steel Woven Wire 20 Mesh - 12x8(30x21cm) Metal Mesh Sheet 1mm Hole Great for Air Ventilation - A4

It came in an envelope with the size of a paper. They are sturdy but easy to cut with a kitchen scissor. I used to cover my air vent and exploded drain holes to prevent roaches or other insects coming in the house.

Bought this to cover vents to keep pests out. They arrived unbent, in a large white envelope, which was enclosed in a box. I’m very happy, and hopeful to keep the spiders out! (For the people commenting on sharpness of the edges: practice safety and be careful. It was easy to avoid cutting myself.)

Works to keep small animals out. Strong but not too hard to cut with good strong scissor. Used it to cover vent openings outside.

Perfect size and quality to make some screens to cover air ventilation. Great purchase, I will probably buy more to use in other rooms. Works great with magnetic tape to fix it.

This screen was exactly what I needed; it handles relatively high heat, grid spacing passes air with little or no resistance, and it easily cut to the shape/size I needed.

Sturdy, good for crafts. If you are doing a larger project consider purchasing more there are 3 small sheets in this package.

These stainless steel screens are great! The screen spacing in tight - like 1/32 small. I am very happy with them

Feels sturdy but can be shaped. I bought these -perfectly sized for our circa 1924 heat registers, to keep small objects - and any mice imported by the cat - out of the ducting. Simple steel wire to attach them, some hand-shaping to snug the mesh to the register, and done. Very nice. Exactly what I needed for this purpose.

These metal sheets were easy to cut to size and apply to openings in steams and on floor. Most importantly, it keeps the mice out!

I needed a fine stainless steel mesh for shrimp proofing an overflow in my aquarium. After poking around online for what # mesh to get, I settled on 30. Super easy to bend or cut with scissors and it looks to be about the right hole size. I imagine #20 would work as well if clogging becomes an issue.
