I appreciate the quick delivery and many size choices of the pure gum rubber stoppers which will be used to plug clay flower pots for a super-efficient low tech, low cost watering technique as described in David Bainbridge's "Gardening with Less Water". I had difficulty finding just the right size stopper until I found WIDGETCO.

Superb service and high quality product
I ordered a mixture of sizes of gum stoppers. I wondered if they would be all mixed together, but they were neatly shipped in separate plastic bags. They are perfect for my projects (hand made wooden salt and pepper shakers). I wanted to use food grade stoppers. Customer servicer answered me promptly when I e-mailed to confirm that the gum rubber is food grade. I am also appreciative of the fact that WIDGETCO keeps shipping costs as low as possible. especially since my order was small. I will order again!

Good selection of Widgets
I'm not sure when I will have time to work with the 10 different items I bought for a back-burner project, but everything is as I ordered, prices are reasonable for my onsey-twosey needs and shipping is fast and well protected for transit.
