The specific EVA material we use is part of the Happy Cube puzzle concept. The bright colours support the differentiation and the flexible soft material carries the constructions as a solid puzzle. This high quality European EVA material is child safe. 

We offer a wide range of colours, fully tailored to your wishes. You can choose between our standard colours, special EVA foam colours or a customised Pantone colour. Since we value fast deliveries, we selected 8 standard colours, which are available in stock. To make the perfect match with your logo, there are more than 300 other colours to make your Happy promotional gift as personal as you want.


As we have these colours in stock we can deliver them ultra fast, even with small quantities. 


We have more than 300 foam colours which are not in stock. A minimum quantity has to be ordered. Send us the details of your desired pantone colour to find the match in our colour line. If you want to know the minimum quantity order of the product of your interest, please contact us.


You can choose another foam colour to perfectly match your logo and design. If it's a colour that we have never used in foam, a lab-test will have to take place. This has an effect on the delivery time. A minimum order quantity is required. Send us the details of your desired pantone colour. If you want to know the minimum quantity order of the product of your interest, please contact us.

The Happy Cube puzzles are made of soft, but solid foam of a very good quality, with no smell: EVA-foam (ethylene vinyl acetate). You can wash the foam Happy Cube puzzles at maximum 30°C, so you can play with them for life. Our foam is partly made from natural rubber. The puzzle is produced without CFC’s (chlorofluorocarbon) and is friendly to the environment. 

Karine Doorsselaer, lecturer at Artesis University College of Antwerp (Belgium), told us the following:

"EVA is one of the least harmful synthetic materials. With optimal combustion, only CO2 and H2O are released, so thermal recycling can be done. The calorific value of EVA is similar to that of oil. So you can say that EVA is a rather environmentally friendly plastic.

However manufacturers (mostly from Asia) profit from cheap but harmful substances, such as formamide, by mingling it through their foam. In itself, this process is totally pointless for the production of EVA and redundant."

We feel the health of people is the most precious on earth. We take care for our manufacturers responsability as market builder. We guarantee our foam is 100% European made and child safe, so that Happy Cube puzzling can be really fun, for children and adults. 

Our high quality EVA-material has been tested and approved by TÜV-Rheinland and TÜV-Hong Kong. The reports include EN71 and ASTM: Phthalates, lead content and flammability… Others like the United States Testing Company and Mc Donalds (lab test in Hong Kong) also approved our Happy Cube puzzle samples.
