Three soft silicone discs that sit over the top of a mug or a glass and seal against the rim by suction. The little bow on top is the lift tab, and the reason they are easy to pull off with one hand.
Diameter: 10.5 cm / 4.13 in, approximately.
Material: food-grade silicone.
Quantity: 3 covers.
Properties: dustproof, leakage proof, reusable.
Their first job is keeping dust and anything airborne out of a drink left standing on a desk or a bedside table. The second is heat: a covered mug of tea holds its temperature noticeably longer than an open one, which is useful if your tea habitually goes cold beside you.
Measure the rim of your own mug or glass against 10.5 cm before ordering, since the seal depends on the fit. They wash easily and go back on many times. Colours may look slightly different on screen.
