We have made this perfectly clear to you in every way! We evaluated many similar products on the market, analyzed and tested their transparency & durability, and conducted temperature & humidity tests. We chose the material with the best value, visited dozens of factories, and chose the optimal manufacturing process for the product. We relentlessly look for ways to make our sign holder even better. A few highlights for Amazing Clarity Acrylic Sign Holder 5 x 7 inches / Upright Plastic Menu Ad Frame / Table Tent: â–º SUPREME CLARITY: In the acrylic industry, the more transparent the acrylic material, the higher its quality and price. We compared numerous acrylic materials and chose the one with the best value. Our sign holder is truly transparent, with minimal yellow or blue undertones. â–º DURABLE: Our sign holders are built from premium quality Cast Acrylic, while most other sign holders on the market are made of cheaper Extruded Acrylic. Cast Acrylic is not only more transparent, but also stronger and more scratch resistant. You'll save money on ordering replacements down the road, and will also help protect the environment by reducing waste. â–º SIMPLE TO USE: Easy to change paper from the top or from the side. It also comes with easy cleaning instructions. â–º MULTI-PURPOSE: Well-suited for businesses, retail stores, restaurants, museums, trade shows, hospitals, etc. It compliments promotional materials, provides a clean and professional image, and helps to convey your message clearly. It is also great for home and personal use. You can use it as a photo frame - put two pictures (back to back) in our double-sided holder and change them whenever you want.
