Hey! Just saw your post and we ship to Brazil, here is our guide to help you pick the perfect mirror:

If you go with an Acrylic Two Way Mirror and it’s smaller than 24" x 48" the shipping is much more affordable than the glass options since it is light and isn’t as likely to break during shipping.

However, if you do want to go with glass, you can still import to Brazil affordably when the mirror is 24" x 36" or smaller and we do have some affordable standard sizes in Glass Smart Mirror & Dielectric Mirror to help keep the cost down. Let me know if you have any questions on our products or guidance on the mirror types.

Ben Eagan just created a comparison video like ours that addresses the film versus the glass two way as well which I thought was super informative:

Hey! Just saw this post and am super excited that we were recommended as a vendor here for the project. I just created a post that details a the mirror types people can find on our website and compares the reflection, transparency, budget and shipping concerns.

We do ship worldwide, fully insured and if something breaks during transit we replace immediately.

Just a quick note on the acrylic based on our findings:
The maximum size we recommend for 1/4" thick acrylic is 24" x 48", any larger than that will be bendy. Some of our customers have tried to use 30" x 50" ish sizes with an IR Touch Overlay and ended up having to switch to glass because it literally interfered with the overlay and wouldn’t work.

For 1/8" acrylic we recommend 12" x 24" or smaller for the best look.

& I’m beaming because I finally convinced the higher ups to offer affordable sizes on the Dielectric Mirror. No one else in the US carries this glass and the display quality is the absolute best on the market while still offering a really nice reflection quality.

Really looking forward to being active in the forum if people are still around to see what questions people have and what kind of need there is for video content on how to create these mirrors.
