Replica TI Exactra 20 Bubble Strip (this is the one with all 7 bubbles) for your custom lightsaber build. This is essentially a perfect copy, indistiguishable from a real TI bubble strip. It will come with the ends sanded off so it can't be used to actually replace a TI strip in a calculator maliciously.
Price $30.00, includes US domestic shipping. Elsewhere is +$5.00.

Please be aware that while these look identical to a real bubble strip, the plastic is not as forgiving if you bend it. It will snap before a real one will, so be careful when handling.
