Question: are they glass?
Document: These are perfect; microwave and dishwash with ease. Kids didn't like them b/c they weren't colorful but that wasn't really the point.
The size is nice for packing for a picnic, not quite what I wanted for my bbq area at home. Lightweight and strong as expected.
I rated the bamboo panda picnic set... 1 star because on the box it has a warning sticker label that states that this product contains chemicals that causes cancer, birth defects, and reproductive harm.
I love the light weight of the dishes. I did not worry about breaking the them as we packed our picnic. The items were small enough to be carried in oversized lunch bag
I love the idea of bamboo, but they did begin to melt in the dishwasher so be careful. I guess you can't have the best of both worlds. Regardless I RECOMMEND THIS PRODUCT.
Great set of &#34;green ware&#34;! They wash up well in the dishwasher or by hand. Purchased for work, the get daily use and are still stain free. Cups are about 7 ounces, yet nice to drink from; however if you use a Keurig, only the espresso size fits in the cup.
Bamboo is a cool and lightweight material for dishes. Who knew?The fact that they are sturdy, dishwasher safe and very lightweight make them perfect dishes for picnic and outdoor use in general. Plus the dishwasher safe element makes you feel a little safer about using them outside because you know once you return home you can clean them really well.
