The GOsili Siliskin Straw Top
is a universal silicone top that stretches over just about any size cup or glass to make it spill proof! Once place on the cup, the suction keeps it in place and it won't pop off while in use.
Siliskin Straw Tops can be thrown in a purse or diaper bag to take with when going out to eat so you won't have to worry about bringing a special spill proof cup.
Siliskin Straw Tops are made of 100% silicone which does not contain toxic chemicals like bisphenol-A (BPA), lead, PVC and phthalates! Silicone also does not transmit unpleasant flavors, promote bacteria or fungus growth and is hypo-allergenic.
Sold in 3 packs in the colors shown and includes one reusable silicone straw.
The attached video explains just how to use the Siliskin Straw Top.
*Please note: While Siliskin Straw Tops have a super stretch, they can still tear if not used properly. Please use with care when taking on and off cups.
