PLASTIC CONTAINERS: This set includes 15 plastic pots with lids and 15 foam liners. The tubs and lids are made from high-quality, food-grade, BPA-free plastic. Each container measures W6 x H8cm (2.36 x 2.48 inches) with an opening diameter of 5.7cm (2.24 inches). The wide opening makes them easy to refill and clean. The jars are dishwasher and freezer-safe but not suitable for microwaves. LEAK PROOF LINERS: Use the foam security safety liners with these jars to stop them from leaking. To keep the contents of your spice pots fresh simply split your liner into two and insert the plain foam side into your lid. Once you have filled your jar, place the security seal on top of your jar. You can now screw the top onto the jar. As our jars have a screw top, the contents will not leak out. These liners make our jars perfect for business use. PLASTIC VS GLASS: As our slime pots are made from plastic, they are more lightweight, durable and resistant to impact than glass containers. They have crystal clear clarity so you can see exactly what is inside without removing the lids. As they are reusable, you can re-purpose and reuse them. Simply handwash, allow to air dry and use time and time again. The smooth surface makes it easy to attach your own stickers and vinyl labels. This makes them ideal for organising or for selling. MULTIPLE USES: These jars can be used for food such as coffee beans, grains, snacks, nuts, beans, sugar, popcorn kernels, seasoning, powder, spices, candy, salt, dry food and legumes. Create homemade slime, lotions, body scrubs, whipped body butter, bath salts, hair cream conditioner and cosmetics to sell. Personalise them and give them as gifts or party favours. They are also helpful around the house, office and shed to store craft items, beads, screws, nuts, bolts, charms and paint. DESIGNED FOR LIFE: Every product in our collection is built with purpose, blending function and style. Our thoughtfully crafted designs ensure lasting reliability and convenience when needed, ideal for any occasion.
