Question: Can you cut my supplied material?
Answer: If you can proof to us what the material is made off and it’s not toxic / flammable, …

Question: Can you cut metal?
Answer: Sorry no, we can’t cut metals, glass or ceramics.

Question: Can you etch on both sides of the sheet?
Answer: In some cases we can etch both sides of the sheet but the problem is it will almost double the cost of your job as it takes twice as long, it’s also sometimes hard to line up 100% so we would only offer this to approved designs.
