stashTHEATTACHABLEPHONECASE Stash is an inexpensive promotional phone case. Stash
has an extendible strap that allows the user to attach
the case to their arm or waist when exercising and then
simply store the strap away during day to day phone case
use.
The size and rising popularity of the global health and
fitness market has resulted in an increase in the money
spent in this sector. However often the participants are
wearing clothing that do not contain pockets. Having
a promotional product that is stylish and promotes a
healthy life style may means people are willing to spend
money in this sector.

MaterialandManufacturing
Silicone is soft, flexible and allows for ease of manufacture. Silicone cases offer good
protection against impact damage along with heat, dust and moisture resistance. Silicone is
lightweight, breaks down easily in the environment and is often recyclable with low toxicity.
Liquid injection moulding has been selected to manufacture both the strap and the case. This
process produces minimal wastage therefore is better for the environment and more cost
effective than other processes.
The branding logo is then printed onto the product. Pad printing with silicone ink is used on
the case.
Assembly is done by manually slotting the cylindrical end of the strap through the bottom of
the case and placing the lid on the other end.
Although this product is primarily designed for the health and fitness market, it could be
attractive to many brands in the travel and leisure market or used in a festival environment.
The large flat surface area allows for many branding opportunities.
Cases are already popular promotional products but a twist on the conventional case will
draw attention to that brand and provide a much more useful, long-lasting, quality driven
promotional product.
USP’s
The silicone case allows for both impact and moisture resistance and room for possessions
while the adjustable strap offers a secure, comfortable fit.
The branded product will be worn with pride for other people to see and admire.
