WarningsRetro Slime Company

At Retro Slime Company (RSC), we have always been dedicated to offering you the highest quality, safest products. Now, we’ve taken a significant step forward in ensuring our slimes meet and exceed industry standards.

🔬 Setting the Standard in Safety

As a small manufacturer registered with the CPSC, we take immense pride in our commitment to safety and quality. We’ve invested significantly in both time and resources to ensure our products undergo testing by an A2LA-accredited laboratory, a certification fully recognized by the CPSC. To the best of our knowledge, we stand out as the first – and potentially the only – company in the cottage industry that produces handcrafted slime and has taken this crucial step. This is a process typically associated with large-scale, mass-produced slime manufacturers. However, we firmly believe that our handcrafted slimes and our valued customers warrant nothing less than the highest standards of safety and quality.

🏷️ Conforming to ASTM D-4236

Our proud declaration? Our products conform to ASTM D-4236, an important standard that guarantees our slimes are safe for use. When you see “Conforms to ASTM D-4236” on our products, you can feel confident knowing they’ve been thoroughly evaluated for potential hazards and are labeled appropriately.

🚫 Clear Warning Labels

We go the extra mile to prioritize your safety. In addition to our rigorous testing and adherence to ASTM standards, we’ve added clear warning labels to all our products. Our commitment to transparency ensures that our customers can use our products safely and correctly.

🌟 Trusted Ingredients for Quality Slimes

At RSC, we believe in providing the best quality slimes that are not only fun but also safe. We do this by using trusted ingredients like Elmer’s glue, a staple in crafting that has proven its safety for years. To ensure our slimes maintain their excellent condition, we’ve developed a Borax solution with the perfect ratio, delivered pre-made in liquid form to reduce the potential for harmful inhalation.
