Refillable Square Jar 50ml

SPD-50

COSJAR’s double layer square jar 50ml is completely made in PP material. The idea is from Mr. Harry S. Trumanour, he said ‘Tact is the ability to step on one’s toes without messing up the shine on his shoes.’ Instead of general sharp-angles-jar, we design this lovely cubic square jar with round angles. Not only prevent the breaking mark during delivery, also caring for baby or child. Regarding the construct of jar, we design double-layer for both cap and jar to avoid cracking apart and to provide better user experience for consumers. To enrich the kinds of product, this cubic jar is available in both 50ml & 60ml, and refillable functional. Once the ingredient has been used up, it can be replaced by a new inner jar. Simply, add a new refilled inner jar, and then continue using, without throwing out the jar. Therefore, with the concept of “Refillable”, it entirely put “Reuse & Reduce” into practice. To do the color injection on this cubic jar is highly recommended. It could be eye-catching from the first sight. If you are looking for having an Eco-friendlier brand image, our SPD-50 refillable PP jar is the best choice.
