RZDEAL Circle Round Stencil Template Artist Design Drawing Aid Tool (Diameter from 1 mm to 37 mm)

Love this a fellow crafter suggest this works great uses it often

I bought this originally for myself (because, let's face it, pumping is basically a science experiment), but this time I gifted it to a new momma. The verdict? Absolute game-changer. The little circle for measuring your flange size is hilariously straightforward—it’s like your nipples have their own fitting room.Yeah, it feels a bit weird to use it for that purpose, but honestly, isn’t everything about pumping a little weird? At least this tool is cheap, efficient, and saves you from playing “guess the size” with pump parts.If you or someone you know is stuck in the flange-size mystery zone, this thing will have them sorted faster than you can say “lactation logistics.” Useful, awkward, and oddly satisfying—a perfect gift for the multitasking milk machine in your life.

Great took to use when sizing for breast pump parts. Works well, would recommend

Great material

Tool is a good size and the material is good and stiff. I do appreciate the fact that the material is see thru. My only complaint is the sizing is a good idea, but the holes are bigger than described by almost half the size.

I actually bought this as a baby shower gift for the new mom to be able to measure what size flange she needed for her pump. It's great for this!

I like this bead sizer. Just having the bead size can be confusing. I need the visual of looking at a hole with the size. This is large enough to have all the sizes I need without being too long, and it's sturdy.

While I have been in Architecture school I have needed this tool more and mope its been strong and durable and also so easy to use sometimes Ill find myself using this more than a compass.
