SF temperature-sensing colour-change sponge
Temperature-sensing and shaped sponges (SF-01 to SF-05)
A functional sponge that changes colour in response to temperature, shifting shade in warm water for both novelty and function.

Product description
The SF temperature-sensing sponge incorporates a thermochromic pigment into the foam. When it meets warm water the colour shifts, and the warmer the water the more pronounced the change — useful both as a novelty feature and as a hint of water temperature.
It can be made in three-dimensional shapes (animals, fruit, cartoon characters and so on) or laminated with scouring pad or open-cell foam to combine visual appeal with practical cleaning. The foam is finely formed and soft, suiting bath use and novelty home products.
Shape, size, colour-change temperature range, colourway and packaging can all be customized, making the series a common way for gift, baby and cross-border e-commerce channels to build a differentiated product.
